Details: This is a professional Helium gas analyzer by Forensics Detectors. Equipped with an advanced thermal conductivity sensor and a built-in pump. Comes factory-calibrated with a NIST traceability certificate. The detection range of He gas is 0 - 100% within 20 seconds at an accuracy of +/- 2% full-scale. Comes factory NIST calibrated from Los Angeles, CA. The detector has a DC3.7V Li-battery 2000mAh that allows for over 6 hours of continuous use. Includes advanced features such as high-resolution LCD, backlight high-resolution LCD, calibration features, and a built-in pump to draw your sample and increase response time and ensure constant pressure and flow for the most accurate He readings.
This helium gas analyzer can draw a gas sample to analyze gas mixes for breathing, trimix scuba, compressed gas, industrial applications, welding, and research & development. It also comes with a probe and tubing to be used as a Helium gas leak analyzer used in various equipment including vacuum equipment, spectrometers, and cryogenics. Since helium is light, it is an excellent tracer gas and can penetrate leaks or compromised seals to then be detected and ultimately find a leak.
Helium is a gaseous compound that is colorless, odorless, and tasteless. It can be isolated from natural gas when the other compounds are liquefied at a low temperature and high pressure - the helium remains as a gas. It finds uses in welding for metals, rocket propulsion, meteorology, cryogenics, breathing operations, technical diving, and scuba.
Included: Gas detector, English manual, USB charging cable, Hard Carry Case, and USA NIST calibration certificate.
