EC Sense
ES1-H2
EC Sense ES1-H2 — Gas
The EC Sense ES1-H2 is a hydrogen gas sensor utilizing electrochemical technology with a measuring range of 0 to 1000 ppm or 0 to 20000 ppm. Recognized as the smallest electrochemical sensor in the world, this device supports both portable and stationary configurations with flow by diffusion or forced flow gas delivery. It delivers an output signal of 11 ±3 nA/ppm and 3 ±2 nA/ppm, features low cross-sensitivity, and provides an expected operating life greater than 36 months in normal operation without approvals.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued EC Sense references — within one business day.
