Testo 327-1 Flue Gas Analyser Standard Kit 0563 3203 80

The Testo 327-1 is designed for domestic gas engineers who need a robust, easy-to-use analyser that can be used every day for the commissioning and servicing of boilers. The device conforms to EN 50379 and BS7967. It features a backlit multi-line display, allowing four parameters to be displayed at once, showing measurements in real-time. Menu navigation is simple to use and quickly becomes familiar. The design of the 327-1 makes it comfortable to hold, plus the magnets on the rear mean it can be attached to the boiler casing.

Test 327-1 measurement parameters

The 327-1 can carry out all the required test procedures for domestic boiler commissioning and servicing. The analyser will measure O2, CO and temperature, plus calculate ratio, CO2 and efficiency.

The unit can also measure flow and return temperatures as well as a full pressure menu for let-by and tightness testing (option accessories required). The testo 327-1 Advanced Kit is available with these required accessories already included.

Advanced protection

To help prevent costly downtime and repairs, the 327-1 has automatic pump protection as standard to help protect the CO sensor from damage as a result of overexposure (4,000ppm range capability)

The built in condensate trap is designed for fast emptying, encouraging the user to do this more often, reducing the likelihood water is drawn into the unit.

Lastly, the 327-1 has a tough rubber over mold to prevent damage from everyday bumps and scrapes. A firm soft carry case is included to safely store the testo 327-1 and accessories when not in use of being transported.

Multi fuel ready

Select from 7 different fuels types, including natural gas, light/heavy oil, Propane, Butane and Kerosene. This device is also Hydrogen ready up to 20% blend.

Test4less proudly operate as an approved Testo distributor and service centre. We can calibrate your Testo 327-1 every year when required, fully in accordance with the manufacturer’s requirements. Your instrument’s warranty will be protected.
