Waterproof hand held pH/ORP/C meters
Two new IP67 waterproof pH meters with the latest probe technology and extended measuring range. Ideal for field or factory use, as the meters are tough and simple to use. The HI-991001 reads both pH and temperature with one probe, and the HI-991003 has a combination probe to measure pH, temperature and also ORP. Both meters have a simple two-button operation. Unit displays pH/ORP and temperature simultaneously on a large LCD screen, with a stability indicator. Calibration is automatic at one or two points with just one button. The user can select between two programmed buffer sets, and screen symbols guide the user through the procedure. When the meter is turned on a battery check advises in percentages the amount of power left. The meter will also retain calibration data during battery replacement. For demanding applications both meters use a stainless steel multi-parameter probe fitted with an amplifier to exclude interference. Supplied complete with electrode, battery, wrist strap and buffer solutions in a hard carry case.
