WalkLAB pH meter HP9010 and Conductivity meter HC9021 from Trans Instruments

Trans Instruments, a specialist manufacturer of pH and conductivity instrumentation for over 30 years, announces the WalkLAB HP9010 pH meter and HC9021 Conductivity meter.

Designed with accuracies matching that of benchtop meters, yet fully portable for onsite use, these meters have a large and simple to navigate backlit LCD display in a rugged ABS casing, which is fully splash and weather proof and has an IP rating of 65. It is simple to use with each measurement automated with an auto-lock system that will display a stabilised endpoint reading. This unique feature allows users, even inexperienced ones, to make calibration and take measurements with minimum handling, temperature or sensor stability errors. Calibration data are stored in non-volatile memory, where in the event of battery removal, data is not erased. It can to store up to 99 sets of measured data memory for pH, mV and temperature stamped with date and time. Users can download stored memory or make continuous data logging on a PC with the optional USB connection kit that comes with an interface software.

The HP9010 pH meter is capable of 5 point calibrations with automatic buffer recognition. Two groups of standards can be selected from ISO standard pH7.00, 4.01 and 10.01 or NIST standard of 6.86, 9.18 etc. Users are able to review the calibration offset and percentage of slope of the electrode. The meter can be attached with an ORP electrode to make redox measurement in millivolts.

The HC9021 conductivity meter is able to make 5 point calibrations over the full range and measured readings are automatically switched to the calibrated range at each of the calibrated point. This greatly enhances the accuracy of the measurement over the entire range. The meter can display units in ppm and conversion factors are adjustable if required. Salinity measurement can be made by switching the display mode to display in ppt, where a separate calibration can be made in NaCl calibration standards.

Both meters are made where ease of use, repeatability and robustness are fundamentals to educational, industrial, textile, aquaculture, commercial and professional users.
