£
-
The GroLine HI98118 pH/temperature tester is our latest pocket meter for measuring the pH of a hydroponic nutrient solution. This modern looking meter is only 0.7" thick and extremely ergonomic, fitting comfortably in your hand. The HI98118 has a very large easy to read LCD display that shows both pH and temperature along with calibration, stability and low battery indicators. All operations are simplified to two buttons. One is for turning the meter on/off and the other for automatic one or two point calibration.
ORP/Temperature Tester - HI98120
£
-
The HI98120 is a waterproof ORP and temperature handheld meter. The housing of this tester is completely sealed to protect against the intrusion of water and is also designed to float if accidentally dropped into a body of water. The HI73120 replaceable ORP electrode is a cartridge design with the stainless steel round connector. With this type of design there are no pins that can bend or break during replacement. The ORP electrode also hase has an extendable cloth junction. This type of junction allows for the renewal of the junction by simply pulling out 3 mm (1/8”) to clear any clogging which improves measurement response time and stability. The exposed stainless steel temperature probe on this meter facilitates a faster, accurate temperature measurement.
pH/ORP/Temperature Combo Tester - HI98121

-
The HI98121 is a waterproof pH, ORP and temperature meter. The housing of this tester has been completely sealed against humidity and is designed to float. Electrode replacement with the stainless steel round connector means there are no pins to bend or break during replacement. When the cloth junction becomes clogged and response time is sluggish, simply pull out 3 mm (1/8”) to clear the clogging which will improve response time and stability. The exposed stainless steel temperature sensor on these models facilitates faster and more accurate temperature measurement.
