Microprocessor-based Portable pH Meter— H-4382

The H-4382 portable pH meter can offer nearly the same performance as a top-of-the-line microprocessor bench meter, making it one of the most popular pH meters on the market. By utilizing an advanced, custom microprocessor, the H-4382 is able to perform pH, ORP and temperature measurements with high accuracy and fast response. The meter measures pH from -2.00 to 16.00 with an accuracy of ±0.01 pH. Temperature is measured from -4.0 to 248.0°F (-20.0 to 120.0°C) with an accuracy of ±0.8°F (±0.4°C). The meter has 3 memorized buffer values (pH 4.01, 7.01, 10.01), and automatic buffer recognition to avoid errors during calibration. When powered on, the percentage of remaining battery life is indicated on the display panel. The mV measurements switch automatically from 0.1 to 1 mV resolution when readings reach ±699.9 mV. Temperature effects are automatically or manually compensated for, from 0 to 100°C (32 to 212°F). The meter is supplied complete with a H-4382.1 double-junction pH electrode, a H-4382.2 temperature probe, four 1.5 “AA” batteries, and a rugged molded carrying case. Meets ASTM D4972.

Pocket pH/Temperature Tester— H-4380A

This pocket pH tester not only displays both pH and temperature simultaneously on one multi-level display, but also features automatic calibration, stability indicator and battery level at start up. The tester is completely waterproof and will actually float if dropped into the sample that is being tested. The meter has an easily replaceable pH sensor that incorporates an extractable cloth junction for longer service life. All readings are automatically compensated for temperature variations and have an accuracy of ±0.1 for pH and ±1.0°F (±0.5°C) for temperature.
