Orbisphere Hydrogen (H₂) TC Sensor with nitrogen purge, protection cap, ext. temp. sensor (20 bar)

Orbisphere Hydrogen (H₂) TC Sensor with nitrogen purge, protection cap, ext. temp. sensor (20 bar)
Product #: 31290TC
Unit Price Contact Hach

Unique thermal conductivity (TC) sensor design

Selective and precise measurement of hydrogen in gaseous or liquid samples

No specific sample preparation required, the gas concentration is measured directly in the sample

Rugged construction can handle harsh plant conditions and high sample pressures

Flexibility of installation for better process control and very low maintenance

What's included?

Sensor only.
Controller, sensor cable, flow-chamber or process connection must be ordered separately.
