| Hanna Instruments HI 98129 Digital Combo pH / EC / TDS meter & Thermometer |
|
The HI 98129 Combo tester from Hanna Instruments is designed for fast, efficient and high accuracy pH, EC/TDS and temperature measurements. No more switching meters to measure the pH and then the EC or TDS of a solution. This tester has a hold feature to prompt the user when to take the reading & a display freeze for easy and accurate recording. Calibration and temperature compensation is automatic. The combo has a replaceable pH electrode cartridge and an EC/TDS graphite electrode which resists contamination. The temperature probe is stainless steel, for faster and more precise measurement. The Combo is supplied complete with pH electrode, 4 x 1.5V batteries and HI 73128 electrode replacement tool. For calibration use the HI 7031M EC solution and the appropriate pH buffers. The replacement probe is HI 73127
Do you need to monitor a higher range of EC/TDS? Consider the HI 98130! It measures up to 20.00 mS/cm (20,000 µS/cm) or 10 ppt (10,000 ppm).
