7.4.5 Combustion air temperature probe (for Condensing Boilers/Furnaces)
The probe to measure the temperature of the combustion air (necessary for an exact calculation of the efficiency
of the appliance) features a stainless steel tube with an adapter for wells of the diameter of 7.5 / 17 mm and K-
type internal thermocouple (Ni-NiCr) to measure the temperature between -4°F and 212°F (-20°C and +100°C.)
The probe comes complete with an 80" (2 m) cable with a connector for connection with the analyzer.
7.4.6

Connection of combustion air temperature probe

As shown in section 7.4 the probe must be connected to the device as follows:
The polarized male connector of the thermocouple must be connected to the lower part of the device in the T2
♦
socket. The improper insertion of the same is not possible thanks to the different lengths of the tips.
7.4.7 Burner pressure verification probe (available soon)
It must be used to measure burner pressure of the gas-powered boiler so it can be regulated in real time. It is
made of a silicone tube, 8x4mm and 1 meter long, complete with connector for connecting to the analyzer.
7.4.8

Ionization current measuring probe

With this special probe it is possible to measure the ionization current of a boiler and check its value depending
on the boiler's technical features.
7.4.9 Measurement of ambient CO (available soon)
Probe for monitoring the concentration of CO and checking safe conditions in the boiler room.

7.4.10 Measurement of differential pressure

The device is equipped with a temperature compensated piezoresistive internal pressure sensor to measure
pressures and depressions. This sensor, mounted onto the device, is of the differential type.
Thanks to the positive and negative pressure connectors, it can therefore be used to measure the differential
pressure by purchasing the special KIT. The measurement range is -1000 Pa ... +20000 Pa.

7.4.11 Connection to PC

By using the USB cable supplied or via Bluetooth connection (optional) it is possible to connect the device to a
personal computer after installing the dedicated software supplied.
Functions:

7.4.12 Connection to battery charger

Supplied with the device is a feeder with output 5V, 2A to charge the internal batteries. In section 4.3 you can see
the socket for the connection of the battery charger to the device. Once it has started charging, the display turns
on and the state of charge of the battery is displayed.
