This pH kit from ETI includes the 8100 meter featuring an easy to read, LCD display indicating pH over the range of -2 to 16 pH with a resolution of 0.01 pH, mV over the range of -1000 to 1000 mV, and temperatures over the range of -39.9 to 149.9°C, with a resolution of 0.1°C.

The pH readings are either manually or automatically temperature compensated over the range of 0 to 100°C. To automatically compensate, it is necessary to utilise a thermistor temperature probe. The tester also incorporates an auto-power off facility that automaticallyturns the instrument off after 10 minutes, maximising battery life.

Other features include the integrated rubber seal to ensure complete water resistance, helping to reduce the possibility of damage in harsh environments. At the touch of a button, the instrument will automatically recalibrate (two-point autocal) itself when used in conjunction with pH buffer solutions. The LCD display features both low battery indication and a user selectable backlight.The unit incorporates an easy to use BNC connector and Lumberg screw-locking type connector, allowing a wide range of interchangeable thermistor probes to be used.

The Extech PH100 pH meter is a robust, watertight (IP57) pH tester. Its flat, changeable measurement electrode allows measurements in liquids, semi-solids, at low flow levels, and even on surfaces. The flat electrode also eliminates electrode breakage and clogged junctions. The readings are temperature compensated for greater accuracy, and the pH and temperatue are displayed simultaneously. As well as the digital pH display there is also a useful pH bar-graph for quick checks. The PH100 has an internal memory for 15 measurements. One-, two-or three-point calibration possible and the meter automatically recognizes buffer solutions. Please order pH buffers separately. Supplied with 4 x CR2032 batteries, protective cap, plastic sample cup, carrying strap and operating instructions.

The GMH 3531 is a handheld meter that is designed to carry out measurements of pH levels, Redox (ORP), rH levels, and temperature. The meter carries out standard or mV_H measurements in ORP mode that allow for automatic conversion to hydrogen system electrodes. Calculation of the rH value is by means of an ORP measurement and by manual entry of pH value or use of previously recorded pH measurement. There is 1, 2 or 3-point calibration with either a supplied buffer, DIN 19266 buffer or manual buffer selection. The GMH 3531 has a display, consisting of two 4-digit LCDs (12.4 and 7mm high), that is easy to read and provides clear and concise instructions and readings. An additional feature of this meter is a calibration interval notice, where the device gives notice of the need for calibration after a selectable time period of 1 to 365 days or can be set to inactive.
