| Microprocessor-based, waterproof |
|
 |
|
| These waterproof and
dustproof testers offer ±1% full scale accuracy and push-button calibration! |
||
| Waterproof, dustproof housing Meets IP67 ratings for highest possible dustproof and waterproof protection. Plus, there’s no need to worry if you drop your tester into water—it floats! Replaceable electrode you can use the same meter body over and over again, which saves you money Push-button calibration calibrate your tester more precisely than trimpot adjustment; no screwdrivers necessary HOLD function freezes reading until you can log it Auto shut-off turns off tester after 8.5 minutes of nonuse; saves your batteries Four models available TDSTestr low: 0 to 1990 ppm (10 ppm resolution) TDSTestr high: 0 to 10.00 ppt (0.10 ppt resolution) ECTestr low: 0 to 1990 µS (10 µS resolution) ECTestr high: 0 to 19.90 mS (0.10 mS resolution) Full reading displayed no need to multiply the readout to obtain actual test values Automatic temperature compensation (ATC) gives you accurate readings even in fluctuating temperatures Calibration kits available Featuring everything you need for calibration, measurement and storage of your waterproof TDSTestr |

right: TDSTestr low shown actual size • Calibration kit includes everything you need for fast, accurate calibration • Calibration button tucked away in battery compartment to avoid accidental recalibration • Replaceable electrodes extend tester life • Testr carrying case stores, transports and protects your tester in the field • Choose from four models for conductivity or TDS measurements |
||
| APPLICATIONS |
||
| • TDSTestr low: Use
for measuring TDS in natural water. Verify reverse osmosis system operation
and tap water quality. Check nutrient solution concentration in hydroponics applications. • TDSTestr high: Use for measuring TDS in salt water, waste water, cooling tower water, and boiler condensate. Check nutrient solution concentration in hydroponics applications. Measure salinity for ponds and recirculating systems. Check saline and chemical levels in pools and spas. • ECTestr low: Use for measuring conductivity (µS) in natural water. Verify reverse osmosis system operation and tap water quality. Check nutrient solution concentration in hydroponics applications. • ECTestr high: Use for measuring conductivity (µS) in salt water, waste water, cooling tower water, and boiler condensate. Check nutrient solution concentration in hydroponics applications. Measure salinity for ponds and recirculating systems. Check saline and chemical levels in pools and spas. |
