The Pioneer's draft shield removes completely for complete cleaning of all components within seconds. Periodic cleaning helps avoid sample contamination and extends the life of the balance. A standard in-use cover provides added protection against spillage and minimizes damage to the display and keypad. Three user-selectable environmental settings help the balance adapt to harsh environments and other disturbances for greater weighing accuracy. An up front level indicator eliminates the need to look behind the balance during the leveling process -- a quick glance at the up-front indicator helps ensure the balance is level prior to each use. An integral security bracket prevents unauthorized movement or theft. An RS-232 interface allows connection to a printer or PC for a record of balance ID, user and project ID, and time and date.

Oakton pH Tester pHTestr 10

Oakton pH Tester pHTestr 10 Reviews



Other Picture


Oakton pH Tester pHTestr 10 Feature

  • Three-point, push-button calibration with auto-buffer recognition for a wide range of results
  • Automatic Temperature Compensation (ATC) for accurate readings in fluctuating temperatures
  • Unique, double-junction electrode design and increased reference gel volume for long electrode life in harsh environments
  • Large, upright, dual-line LCD display screen for ease of viewing, and to display indicators
  • Waterproof, dustproof housing that sits on a flat surface and the meter floats, if dropped in liquids

The Oakton 35634-10 pH Testr 10 is a handheld, waterproof and dustproof meter that floats, if dropped in liquid, and features a replaceable double-junction electrode within its reusable tester body. A portable meter is commonly used to measure the pH of substance such as food, beer, or wine, and is also used to test cleaning water, rinse water, and wastewater, in lab, industrial and food applications. This microprocessor-based meter has Automatic Temperature Compensation (ATC) for accurate readings in fluctuating temperatures, and three-point, push-button calibration with auto-buffer recognition of US and National Institute of Standards and Technology (NIST) standards for a wide range of results. The meter’s waterproof and dustproof housing has an Ingress Protection (IP) 67-rating for protection against solid objects or liquids. It has a large, upright, dual-line LCD screen for ease of viewing, error messages, a hold function which freezes readings for recording, and an auto shut-off that turns the meter off after 8.5 minutes of nonuse to extend the life of the batteries. It has a protective cap to reduce contamination and a double silicone O-ring for ease of electrode module replacement.

The 35634-10 tester has an operating temperature from 0 to 50 degrees C (32 to 122 degrees F). pH range - 1.0 to 15.0, resolution 0.1, accuracy + or - 0.1, calibration up to three points with US or NIST buffers at 4.0, 6.86/7.0, or 9.18/10.0. Its dimensions are 6.5 (h) inches x 1.5 (w) (16.8 x 3.8 cm) and it weighs 3.25 ounces. The tester works with four 1.5 V alkaline batteries (not included) for up to 500 hours of continuous use (Eveready A76 or LR44 equivalent replacements).

pH testers measure the acidity or alkalinity of a substance. They are commonly used for water testing, and for biological sample analysis in hydroponics, aquaculture and agriculture.

Oakton Instruments manufactures an array of scientific instruments for research, industrial, and educational uses. Since 1991, Oakton has distributed a wide variety of instruments such as meters, electrodes, and transmitters. Oakton is based in Vernon Hills, IL, and has facilities in Europe, Asia, and China.

Hanna Instruments HI 84432 Fruit Juice Titrator and pH Meter

Hanna Instruments HI 84432 Fruit Juice Titrator and pH Meter Reviews



Other Picture


Hanna Instruments HI 84432 Fruit Juice Titrator and pH Meter Feature

  • Log on demand up to 100 samples (50 for pH measurement; 50 for titration results)
  • GLP feature, to view last calibration data for pH electrode and pump
  • The HI 84432 mini titrator uses a method based on the Official Methods of Analysis of AOAC International.
  • The fruit juice is titrated with a sodium hydroxide solution until the end point at 8.2 pH is reached (determined by potentiometric method).
  • The HI 84432 has a built-in pH meter for pH measurement (electrode and meter must be calibrated).
The HI 84432 is an easy to use microprocessor-based automatic minititrator and pH meter designed for the rapid and accurate analysis of Total Titratable Acidity in fruit juices. By eliminating subjective factors including color indicators, errors in mathematical calculations or erratic titrant additions from the measurement, the HI 84432 makes Total Titratable acidity analysis precisely. This will quickly become a valuable acidity analysis tool of fruit juices. A clear and well-designed user interface makes the instrument intuitive and simple to use. A dedicated HELP key aids in set-up, calibration, status and troubleshooting. By simply pressing the START key, the HI 84432 automatically starts pump operation and titrates the sample to the end point. The HI 84432 has a simple and accurate peristaltic pump to ensure the best accuracy and repeatability. By performing pump calibration with the Hanna standard provided, the instrument accuracy is assured. The instrument employs a powerful and effective built-in algorithm to analyze the pH response to determine the exact pH endpoint, then uses this to make the necessary calculations. The Titratable Acidity determination is instantaneously displayed in selected measurement units on the large dot matrix display. The instrument is ready for the next analysis immediately. HI 84432 minititrator is supplied complete with: • HI 1131B pH electrode • HI 7662-M Temperature probe • HI 84432-50 Titrant solution (100 mL) • HI 84432-55 Pump calibration solution (100 mL) • HI 7061M Cleaning solution (230 mL) • HI 70300M Storage solution (230 mL) • HI 7071 Filling solution (30 mL) • HI 7004M pH 4.01 buffer solution (230 mL) • HI 7007M pH 7.01 buffer solution (230 mL) • HI 70082M pH 8.20 buffer solution (230 mL) • Two 100 mL beakers • Tube set with dispensing tip • Stir bars (medium 2 pcs.) • 12 Vdc power adapter • Instruction manual

Models are available in a variety of sizes covering the range from 0.1uL to 5mL. Minimizes Strain and Discomfort The Transferpette features a hook-shaped handle design, light weight, and side-mounted pipetting key work together to minimize the strain and discomfort of repetitive pipetting. Corrosion-Resistant and Autoclavable These pipettes are corrosion-resistant, autoclavable, feature a narrow-shaft design and are compatible with most tips to ensure their effectiveness in almost any application. Dedicated Controls Simplify Pipetting Every Transferpette function has a dedicated control to simplify operation as well as limit inadvertent tip ejection or volume adjustment. Pipette Even Submicro Volumes The Transferpette 0.1-1uL can pipette small volumes with unparalleled accuracy and precision. When used with BRAND nano-capTM tips. It drastically reduces the air column between the piston and sample, a major source of error when pipetting volumes of less than one microliter. Make Calibration Adjustments in Seconds Adjustable volume versions of the Transferpette single channel pipette are equipped with Easy CalibrationTM technology to simplify ISO/GLP compliance and eliminate the need for inconvenient offsite recalibration. Thoroughly Tested Every Transferpette is subjected to a thorough series of tests and is supplied with a performance certificate as well as a three-year warranty.
