Twin pH Waterproof Meter

The intelligent pocket-size pH meter that reads temperature & has automatic temperature compensation

The rugged Twin pH meter speeds and simplifies your pH measurements. Put a few drops of sample on the flat sensor, immerse the sensor in your sample or scoop up a bit with the spoon shaped sample well. And don't worry about splashing: it's waterproof! The dual action sensor guard protects the electrode and captures samples from buckets, lakes, streams, or running water. The flat sensor allows measurement of small samples, pastes, powders or solids while Autocal simplifies measurement and promotes accuracy. This compact pH meter is perfect for lab, plant or field!

Twin pH Display

With Sliding Lid Open With Sensor Guard Open
Immersion Measurement Flat Measurement
Immersion Measurement To take measurement of water quality in rivers or lakes, just immerse the sensor in the water and note the measurement results.
Flat Measurement Measure solids or powders
Just place the sample directly on the sensor. Before measuring earth, powder, and other solid samples with low moisture content, add a drop or two of deionized water.
Flat Measurement To measure in drops
Use an eye-dropper to drop about 0.1 ml of the sample solution on the sensor.
Flat Measurement To measure rigid surfaces
To measure surface pH, wipe the surface of the sample with a sampling sheet dampened with deionized water and place the sheet on the sensor.
Scoop Measurement
Scoop Measurement To take measurement of water quality in rivers or lakes, just immerse the sensor in the water and note the measurement results.

TwinN03 - Compact Nitrate Ion Meter


Flat sensor enables easy measurement with only a few drops of sample

TwinN03

The B-340 series is a compact and robust nitrate ion meter using flat sensor technology. This technology
allows very small sample sizes to be measured (minimum sample size 0.3 ml). The instrument is simple to calibrate and easy to use. Combine this with its compact pocket size and you have an instrument that can be used for various applications in the lab or oout in the field.
