Cond./TDS/Salt/Temp Water Proof Meter Manufacturer,Supplier and Exporter in India

Product Code : EL-CM-2194
Jlab Export is a leading Cond./TDS/Salt/Temp Water Proof Meter Manufacturer,and suppliers in India

If this pocket tester slips into a pond or sampling bucket it floats, and its case is water-proofed to IP-57. It reads conductivity, TDS, salt and temperature on a large LCD, with automatic temperature compensation at 2% per °C and a TDS factor of 0.67. Hold, max/min and °C/°F switching are built in, and it turns itself off after 10 minutes.

Field Survey Activities for Students

Environmental science groups can take the tester on a water-quality walk, testing tap water, a school tank, a pond and a drain outlet. At each point they record conductivity, TDS and salt, using the hold and max/min functions to fix readings for the field book. The Backpack Water Quality kit adds tests for other parameters on the same samples.

Back in the lab, students check the tester with the standard calibration solution supplied, then compare TDS in tap, RO and bottled water. Another short exercise adds Sodium Chloride to water a little at a time and watches the salt reading climb with each addition. The Testing Drinking Water kit lets the class set these results beside strip tests for hardness, chlorine and fluoride.

Frequently Asked Questions

How do I calibrate the tester?
Pour a little of the 50 ml standard calibration solution into a clean cup, dip the sensor end and let the reading settle. Then use the push-button calibration to set the value of the solution. Throw away the used portion instead of pouring it back into the bottle.

Will the tester survive a drop into a tank or pond?
It is water-proofed to IP-57 and floats, so it will not sink if it slips from your hand into water. After field use, rinse it with clean water and let it dry before packing it in its carrying case.

Why does it use a TDS factor of 0.67?
The tester converts conductivity to TDS by multiplying by 0.67. A meter set to a different factor will give a different TDS figure for the same water, even when both are working correctly. Compare TDS only between instruments that use the same factor.

Can I use it for hydroponic nutrient solutions?
Yes. Nutrient solutions are checked by conductivity, and the mS range up to 20.00 mS covers them. Rinse the sensor in clean water after each nutrient sample, because salts left drying on it raise the next reading.

Can it test sea water?
Not at full strength. Its top ranges end at 20.00 mS for conductivity and 12.00 ppt for salt, and sea water reads above both. It suits fresh, RO and drinking water, and brackish samples within those limits.
