Purchasing Guide & Expert FAQ

How do I select between different sensor types in the XNX series?

Choose infrared sensor options for hydrocarbon monitoring where catalytic bead poisoning is a risk. Select electrochemical sensors for toxic gas detection applications.

What causes a calibration fault during routine maintenance?

Accumulated dust on the optical lens or unstable reference voltage typically causes calibration failures. Clean the optics and verify power supply stability.

Can the HART protocol communicate over long cable runs?

Yes, the 4-20mA current loop supports reliable HART digital communication over distances up to several thousand feet when using shielded twisted-pair cables.

What are the payment and shipping terms for urgent orders?

We support secure B2B payment methods and dispatch orders within 24-48 hours via trusted couriers including FedEx, UPS, and DHL.
