NEW! OAKTON® CTSTESTR 50P WATERPROOF CONDUCTIVITY, TDS, SALINITY TESTER:
This CTS tester make measuring water quality easier and faster. The large display offers a better viewing angle, has indicators for battery life,
readiness, and calibration, and shows both the parameter and temperature readings at the same time.
To enhance field use, the cap was redesigned to be leakproof and can be attached to the top of the meter when not being used-
no more lost caps! The cap features a fill line, so you know how much sample you need for an accurate reading when using the cap as a sample cup.
The wider design provides a base to keep the meter upright for hands-free measurements. The keypad features fourth key to simplify menu navigation
while keeping convenient one-touch calibration. The housing is compatible with lanyards to prevent losing or dropping, but is still waterproof.
Features:
- Immerse and read with pin-style sensor
- Redesigned leakproof cap functions as a sample cup and stabilizing base to stand the meter upright
- Automatic temperature compensation ensures accurate reading in varying environments
- Easy-to-navigate interface for quick setup and calibration

HANNA COMBO METER: PH / CONDUCTIVITY / TDS / TEMPERATURE
The new waterproof HI98129 & 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 () 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.
Choose your Combo according to the proper EC / TDS ranges for your application:
HI98129 Combo; EC - 0 to 3999 uS/cm; TDS - 0 to 2000 ppm with HI73127 pH electrode,
