Want portable gas calibration without cylinders or bulky equipment?

The Span Chek™ 2400 from KIN-TEK is your grab-and-go solution for accurate, NIST-traceable gas standards, ideal for ambient air monitors, detectors, and fence-line systems. It delivers repeatable multi-point concentrations directly at the sensor using up to four Trace Source™ disposable permeation tubes.

An internal micro-compressor and purified ambient air eliminate the need for external sources. With stable temperature control (30–60°C), it supports a wide range of concentrations from sub-ppm to 100 ppm.

Compact, rechargeable, and easy to use, Span Chek™ 2400 fits seamlessly into field, lab, or industrial workflows. Ditch the heavy gear and calibrate with confidence, anywhere.
