With these powerful waterproof testers, you can easily measure pH, EC/TDS, temperature,and now ORP, anywhere. Attention to detail is evident in these advanced instruments with features such as replaceable electrode technology and stainless steel temperature probes for faster, more precise measurements. The EC/TDS meters have graphite probes for fast response and contamination resistance.

At startup, each tester performs a self check then displays the remaining battery level assuring proper working condition. A stability indicator tells you when to take the reading and a hold button freezes the display for easy and accurate recording. All information is displayed on a redesigned LCD that gives you the complete picture at a glance. On-screen Battery Life When turned on, the LCD indicates the percentage of battery power remaining.

Replaceable Electrodes
Hanna uses exclusive replaceable cartridge electrodes. The stainless steel round connector of the electrode
means there are no pins to bend or break during replacement.

Rejuvenating pH Junctions
The pH replaceable electrode features a pull-out cloth junction. When the cloth junction becomes dirty from routine testing, simply pull out 3 mm (1/8”) to rejuvenate the electrode.

Contamination Resistant Conductivity Electrode
Hanna’s graphite conductivity electrode resists contamination from salt deposits in the solution.

Close Proximity Temperature Probe
An exposed temperature probe provides faster response times. Its close proximity guarantees more accurate temperature compensated readings.
