Probe for measuring the ionization current
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.
Calibration certificate
The instrument is calibrated by comparing to National Calibration Standards provided by a Metrology Lab.,
certified periodically by internationally recognized laboratories.
A calibration certificate is provided with each and every instrument where every parameter is accompanied by the
relevant nominal value, measured value, permissible error tolerances and measured error.
Electromagnetic compatibility
The instrument was designed to comply with Council Directive 2004/108/EC governing electromagnetic
compatibility.
2.3 Measurement Ranges and Accuracies
All data relative to concentration accuracies are referred to an instrument operating at a constant temperature
within the correct operating range (-5°C .. +45°C), being in operation for at least 15 minutes, powered by its
internal battery and after completion of auto-zero procedure.
Notes: (1) The maximum CO

value displayed depends on the type of fuel.
(2) Stated precision includes error of the external sensor RTD Pt100 class A DIN 43760 (1980).
(3) Stated precision includes error of the external sensor type K thermocouple class 1 IEC584.
(4) Pressures greater than 300 inH
