Designed specifically for the detection of gas leaks, the GasCheck range of gas leak detectors respond rapidly to any gas, or gas mixture. The advanced micro-thermal conductivity sensor of the GasCheck G accurately detects the smallest of gasleaks down to cc/sec, mg/m³ or ppm levels. The GasCheck IS gas leak detector is the only ATEX approved, Intrinsically Safe leak detector on the market. Its Intrinsic Safety proves an ideal tool for use in areas classified as zone zero flammable, and can safely detect flammable gases. GasCheck gas leak detectors are conveniently calibrated against helium and are particularly sensitive to ammonia, argon, butane, hydrogen, SF6 and refrigerants.
SF6 Gas Leak Detector Leak Check P1 : P
Highly sensitive, detection guaranteed every time.
SF6 LeakCheck P1:p is designed for the location, leak testing and measurement of SF6 leaks in high voltage electrical switchgear. The revolutionary SF6 leak detector rapidly detects leaks down to 1 x 10-8 ml/sec, with a response and clear down of less than 1 second. The instrument’s award winning Negative Ion Capture (NIC) technology with non-radioactive source eliminates problems of registration, storage and transportation.The LeakCheck P1:p SF6 leak detector is unaffected by large leaks. The detector will continue to remain uncontaminated even after exposure to 100% SF6 gas.
Applications
High voltage switchgear leak testing
- Switchgear commonly engages SF6 as a highly insulating medium to prevent sparking between high voltage components. Impact Instruments successfully detected SF6 leaks on 11 and 66 KV swithgear as well as ring main units which were leaking. SF6 is costly to replace, causes ozone depletion in the upper atmosphere, and its loss may result in catastrophic failure of equipment.
GIS Leaks
- Gas insulated switchgear is filled with SF6, Impact Instruments performed many hugely succesful tests using the Leak Check P1 : P, at Eskom and municipal sites. The Leak Check P 1 : P was even found to be "too" sensitive at times. Detection of volatiles in industrial environments is an essential part of maintenance of health and safety of personnel, and can be carried out by continuous monitoring of personnel or at appropriate fixed loactions
SF6 AreaCheck P2 – Fixed SF6 Leak Detection
- Detect and alarm to leakage in indoor GIS (gas insulated switchgear) substations
- Protect personnel, reduce emissions and wastage
Designed for fixed continuous SF6 area monitoring, the AreaCheck P2 with 12-point network controller rapidly detects low-level SF6 leaks.The fixed SF6 leak detector utilises relay output for immediate awareness of detected leaks, and presents no cross sensitivity with any other gas or moisture in the air. The AreaCheck P2 has no filter problems due to its minimum air intake (compared to pump operated 
systems). Instrument setup is carried out easily via a computer or network interface, allowing optimal protection from unauthorised access. The SF6 AreaCheck P2 has a built in low flow alarm and self-diagnostic testing. Serviceable components are comprised in the user exchangeable SmartSensor, with a lifetime of up to 12 months. Measuring stations are maintenance-free, ensuring instrument downtime is minimised. The SF6 leak detector can be effectively used as a stand-alone instrument or with the P2 network controller and up to eleven other SF6 AreaCheck P2s.
