The sensing element is comprised of a metal oxide semiconductor layer formed on an alumina substrate of a sensing chip together with an integrated heater. In the presence of a detectable gas, the sensor’s conductivity increases depending on the gas concentration in the air. A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to the gas concentration. The TGS 2600 has a high sensitivity to low concentrations of gaseous air
contaminants such as hydrogen and carbon monoxide which exist in cigarette smoke. The sensor can detect hydrogen at a level of several ppm. Due to the miniaturization of the sensing chip, TGS 2600 requires a heater current of only 42mA and the device is housed in a standard TO-5 package

Features:

1. Low power consumption
2. High sensitivity to gaseous air contaminants
3. Long life and low cost
4. Uses a simple electrical circuit

As an upgraded version of this new generation, the Industrial Grade Analog ORP Sensor Meter PRO ORP probe employs a platinum indicator electrode and silver-silver chloride reference electrode, which makes it available for 24-hour online ORP monitoring and greatly enhances product durability. The new signal converter adds a more stable voltage reference so that the sensor readings would be no longer affected by supply voltage fluctuations. Besides, there are screws, copper columns, and waterproof connectors included in the accessory packet to help you conveniently build up an ORP monitoring system.

ORP(Oxidation-Reduction Potential) is a measure of the ability of oxidation and reduction of an aqueous solution, which is the relative degree of oxidizing or reduction. The unit is mV. If the oxidation-reduction potential is high then chemical oxidation is strong, while if the potential is lower then oxidation is weaker. The positive potential means that solution shows a certain degree of oxidation, while the negative potential means that solution shows a certain degree of reduction. ORP is an important index of water quality detection, although it can not separate water quality independently, it can be combined with other water quality indexes to reflect the ecological environment better.

Features:

1. More  durable
2. 24-hour online ORP monitoring
3. The new signal converter adds a more stable voltage
