The HI70010P is a premium quality pH 10.01 calibration buffer solution. Each sachet has the lot number and expiration date stamped on it and is made of light block foil ensuring freshness each time one is opened. 

Accurate. Waterproof. No more switching between meters for your routine measurements with the HI98130 pH and conductivity tester.

When the original DiST® (Dissolved Solids Tester) was first introduced, conductivity and total dissolved solids measurements became easy and affordable. The DiST’s ease of use, in combination with its affordability, made it the standard in EC and TDS measurement. Hanna continues the standard in EC and TDS testing with the DiST®5.

The DiST 6 Tester includes features such as: a replaceable graphite electrode, adjustable TDS ratio, °C or °F measurement, Automatic Temperature Compensation (ATC) with adjustable β, battery level indicator, stability indicator, automatic shut-off and automatic calibration.

The HI88703 is a high accuracy (±2% of reading plus 0.02 NTU) Turbidity Benchtop Meter. The meter is supplied complete with AMCO-AEPA-1 primary turbidity standards used for calibration and performance verification.

HI70300M is a specially formulated electrode storage solution that can be used to store your pH electrode*. To ensure the best response time, the sensor tip and the reference junction of the pH electrode should be kept moist when not in use. Placing the pH electrode in a small glass filled with storage solution or replacing the solution in the protective cap is a n easy way to store the electrode. The HI70300M should also be used to rehydrate the electrode after cleaning by soaking for at least one hour before taking measurements.

HI83306 is a compact, multiparameter photometer for use in the environmental lab or in the field. The meter is one of the most advanced photometers available with a innovative optical design that utilizes a reference detector and focusing lens to eliminate errors from changes in the light source and from imperfections in the glass cuvette.
