Information on the calibration of newly purchased equipment and what it means to you.
Calibration and its certification comes in varying forms on new equipment and in this section, we will break it down into the three areas that we use to classify calibration state at the point of purchase.
Manufacturers Calibration Certificate
This is a calibration certificate offered by the manufacturer supplied with the tester. This is also known as an end-of-line certificate or manufacturer’s certificate. These certificates vary depending on the manufacturer and product. They will not have your company's name on them and don’t always show proven test results.
Where applicable we will include the following statement relating to the item/s on the products page under the heading *Important Calibration Information.
This instrument comes complete with the manufacturer's calibration certificate. Please be aware that these certificates are generic and may also be time-lapsed.
If you would prefer a personalised full traceable calibration certificate applied to the equipment before dispatch, then please select this option from the drop-down menu above, an additional calibration charge will apply.Manufacturers Certificate of Conformity
A manufacturer's certificate of conformity is not a calibration certificate. It is merely a statement that the equipment has been produced to operate within its intended application, it has no traceable certificate or constitutes any defined results for accuracy before leaving the manufacturing process.
Where applicable we will include the following statement relating to the item/s on the products page under the heading *Important Calibration Information.
This instrument comes with a ‘manufacturer's certificate of conformity’. It is important to understand that this does NOT constitute a ‘calibration certificate’. A certificate of conformity merely states that the equipment has been designed and produced to meet the requirements of its intended application.
Where calibration of an instrument is possible we will offer this as a separately purchasable item and may be selected from the drop-down box above. You will be sent a full traceable calibration certificate produced in our laboratory and applied with your details as required.Personalised traceable calibration certificate from isswww
This is a calibration certificate created by us at ISS. This certificate is fully traceable to national and international standards. The certificate will show your company's details, tester information, proven test results and the equipment used to carry out the test. Nearly 90% of all calibrations we do are done in-house in one of our many fully equipped laboratories. You can add this service to your order on the product page before you checkout.
Where applicable we will include the following statement relating to the item/s on the products page under the heading *Important Calibration Information.
We are on occasion able to offer FREE calibration on certain products at their point of sale (newly purchased equipment only) please look out for the following badge on the product's page to take advantage of this free offer.

TPI 725L Combustible Gas Leak Detector
Find the source of combustible gas leaks in valves, pipes, and fittings.
40 PPM methane sensitivity, detects combustible gases including: Methane, Butane, Propane, Gasoline, Diesel and Kerosene. Tick rate can be nullified to eliminate background gas concentration and pinpoint the leak source.
- 40ppm methane sensitivity and bearing defects
- Trace natural gas lines and fittings for leaks frame to failure
- Check gas equipment for leaks
- Test propane tanks, fittings, lines, and heaters for leaks
- Check propane tanks, fitting lines, and heaters for leaks
- Test confined spaces for gas build-up
In a clean air environment, press the ON/OFF key to turn the 725L on. Both LED’s will flash as the unit initializes and auto zeroes. When the green LED above the ON/OFF switch flashes and a tick is heard the 725L is ready for use. Trace gas lines, fittings, tanks, and containers for leaks.
Approach suspected leak areas with the sensor. When a leak above 40ppm is detected the 725L tick and green LED flash rate will increase. When the tick rate increases press and release the ON/OFF key to nullify the tick and continue to approach the suspected leak area with the sensor. Continue to nullify the tick when the rate increases until the location of the leak is found. If the tick slows or stops on its own the concentration level has decreased. Move back in the opposite direction to find the leak again. If the leak reaches 1000ppm or above the high LED will illuminate (see below).
To turn the 725L off, press and hold the ON/OFF key down until the unit powers off.
High: >1000ppm Methane detected
Tick: >40ppm Methane = Increased tick and green LED flash rate.
Ready for use = Slow tick and green LED flash rate
Low batteries = Red LED
On/Off: Press to turn power on and auto zero
Press to nullify tick rate to pinpoint leaks
Press and hold to turn power off
