Combo pH/Conductivity/TDS/Temperature Testers

Just about everything you need in one compact tester, the waterproof, buoyant Combo is ideal for laboratory and field use.

It features a large, easy-to-read, dual-level LCD that displays pH or EC/TDS and temperature simultaneously, one-handed push-button operation, and automatic shut-off.

pH and EC/TDS readings are automatically compensated for the effects of temperature.

The Combo has a replaceable pH electrode cartridge with an extendable cloth junction, so your meter does not have to be thrown away once the pH sensor is exhausted.

It also has an EC/TDS graphite electrode that resists contamination by salts and other substances, thereby extending the life of the meter.

The temperature sensor is exposed to provide fast response time, and its proximity to the pH and conductivity electrodes guarantees more accurate temperature compensated readings.

Both units are supplied complete with protective cap, electrode removal tool, four 1.5V batteries, and operating instructions.

Combo pH/Conductivity/
TDS/Temperature Testers

All pH meters require calibration to provide accurate results.  If you do not already have buffer solutions available for calibration, we recommend our 25304 buffer sachets.  This product includes ten 20mL ready-to-use buffer packets, five each of pH 4 and pH 7 buffers.  We also recommend purchasing our 25310 electrode storage solution to protect the electrode when not in use.

Manufactured by Hanna Instruments.
