The new waterproof 50-HI98129 and 50-HI98130 Combo testers from Hanna are designed for high accuracy pH, EC/TDS and temperature measurements.
No more switching meters to measure the pH and then the EC or TDS of a solution. At startup, Combo performs a self check then displays the remaining battery level to assure proper working condition. These testers also have a stability indicator and hold feature to prompt the user when to take the reading & freeze the display for easy and accurate recording. Calibration and temperature compensation is automatic, while the EC / TDS conversion factor and temperature coefficient factor (ß) are user adjustable for application specific measurements. For calibration in pH, the user may choose between standard or N.I.S.T. buffer sets.
The combo has a replaceable pH electrode cartridge with an extendable cloth junction as well as an EC/TDS graphite electrode which resists contamination by salts and other substances that come in contact with the electrode. These new pH / EC / TDS / Temperature meters have a stainless steel temperature probe for faster and more precise temperature measurement. Fast, efficient, accurate and portable, the Combo pH, EC/TDS and temperature tester meets the requirements of your routine multi-measurements.
