- Run off distilled water, eliminate re-ordering worries.
SIM Hydrogen Sensor – Safety for Hydrogen Gas in the Lab
The SIM Hydrogen Sensor is designed to monitor GC ovens using H2 as a carrier gas.
- Continuous monitoring of the oven air.
- Eliminate the risk of any explosion.
- Catalytic pellistor sensor for long-term stability.
- Visual and acoustic alarms.
- Automatic switching to inert carrier gas.
Electronic Leak Detectors
We are fortunate to offer two of the finest leak detectors on the market; both are battery-powered for portability and feature shock-isolation designs to enhance their ruggedness. Contact our Technical Team to discuss your specific needs. They’ll be able to walk you through the features of both units and help you determine which is best for your lab.
Restek - Leak Detector
- Quickly identifies small leaks to prevent damage and downtime.
- Detects various gases and shows leak severity with LED display and audible alarms.
- Operates during charging or up to 12 hours between charges.
- Includes universal AC adaptor and USB cable for flexible charging.
GL Sciences - Leak Detector LD249
- Includes compact sensor for quick, accurate leak detection.
- Detects leaks using thermal conductivity differences.
- Alerts with LCD display and audible alarms.
- Avoids contamination risks compared to traditional methods like Snoop.
