Karya Mandiri Techindo has a wide range of Hanna products – search by type, or model, or filter by brand to find the one you are after. If you still can’t find it contact us..

The HI-991300 meter features two operation button and is simple to use. All operations and settings, including calibration buffers and temperature scale selections, are made through these two buttons. It has a waterproof and compact casing rated for IP67 conditions and a large tri-line display. The meter has automatic pH calibration at one or two points and a single conductivity calibration. Other user selectable features include different TDS factors from 0.45 to 1.00, and a range of temperature coefficients from 0.0 to 2.4% for better conductivity or TDS solution temperature compensation. The meter is supplied with a multi-parameter probe specifically designed for this meter.

Each meter is supplied complete with:

HI-12883 pH/EC/TDS probe with built-in temperature sensor, DIN connector and 1mm cable
pH 4.01 & 7.01 buffer sachets

About the HI-12883 probe

The HI-12883 multi-parameter probe, incorporates a domed shaped pH bulb rated from 0-13 pH, a single junction Ag/Cl reference electrode with gelled electrolyte and a retractable cloth wick junction, a graphite EC/TDS cell, and a temperature sensor in one convenient, rugged polypropylene body. In addition, to ensure against interference from transient electrical noise to pH, a solid-state pre-amplifier is integrated into the probe. The probe is rated from 0 to 50°C.
