This spear tip pH sensor/meter kit can directly stab into semisolid material to measure the pH value. It can be used to measure pH value of wet soil and various foods. 

DF-FIT0348

This pH combination electrode is made of sensitive glass membrane with low impedance.It can be used in a variety of PH measurements with fast response, good thermal stability.It has the good reproducibility, difficult to hydrolysis, and basically eliminate the alkali error .In...

DF-FIT0212

This non-contact liquid level switch can be triggered when the liquid level fall below the sensor attached to the outside surface of a non-metal container.

DF-DFR0198

This is a waterproofed version of the DS18B20 Temperature sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you ...

DF-SEN0216

The Water Flow sensor measures the rate of a liquid flowing through it. The YF-S401 water flow sensor consists of a plastic valve body, flow rotor and hall effect sensor. It is usually used at the inlet end to detect the amount of flow. When liquid flows through the sensor, a ...
