GPPS-evo Laboratory Gas Pressure Proving System
The GPPS-evo is a laboratory gas pressure proving system with the ability to monitor up to four gas sensors.
Gas Pressure Proving
The gas pressure proving is by Medem’s patented method of dynamically measuring the pressure differential across the solenoid valve when performing a downstream integrity check. This method stops nuisance tripping of the gas supply. The addition of the LCD makes this system very easy to use providing clear messages giving real information rather than just LED indications.
Flexibility
The GPPS-evo is designed to perform a downstream integrity check of pipework and appliances which could be left open to atmosphere, such as a laboratory.
In-line with the updated legislation of BB101 and IGEM/UP11/Edition 3 the system can also monitor the CO2 level when fitted with a Medem detector displaying the PPM.
CO2 is considered a primary indicator of air quality, with the latest legislation setting maximum limits for levels within educational facilities.
Carbon Monoxide, Natural Gas and Oxygen detectors can also be monitored.
An auto-stop timer is incorporated to help prevent unauthorised use of the gas out-of-hours.
There are several ‘engineer functions’ which can be used to aid in the set-up of the system.

GPPS-evo Laboratory Gas Pressure Proving System Warranty and Service
All our products come with a 5-year warranty
Medem’s industry leading five-year warranty is a demonstration of the company’s confidence in the quality and design of its products.
This applies to the main panels and sender units, gas detectors carry a 2-year warranty.
Why not let us install your system and receive a 10-year Warranty?
Where we’ve commissioned an installed system, the warranty is extended from five to ten years. At the time of commissioning, photos and gas pressure readings are recorded along with other relevant details of the installation. A 24-hour helpline number and the serial number is attached with the panel and all details are then entered on to the Medem database.
Service
The panel and sensors must be re-commissioned and tested every 12 months as a minimum but with consideration of every 6 months dependent on gas type and environment. Medem offers cost-effective yearly service plan options which include detector exchange
