The design of the handheld combustion analyser "CASPER" is clean and ergonomic with an extremely clear and
user-friendly keypad.
"CASPER" immediately suggests just how even the most sophisticated engineering can give life to an incredibly
comfortable and easy to use work instrument.
evised to analyse flue gases, monitor the pollutants emitted and measure environmental parameters,
"CASPER" uses two electrochemical cells that provide the oxygen and carbon monoxide values while a third cell
is used to measure the pollutants NO and NOx.
Two external sensors measure the environmental parameters; it is also possible to measure flue draught and
carbon black (with external accessory) and, with the measuring range of up to 200mbar, system pressure and
pressure in the combustion chamber can be measured and the pressure switches checked.
"CASPER" is designed for eleven main types of combustible substances, among which natural gas, LPG, iesel
fuel and fuel oil. Another 16 types of which the chemical composition is known can be entered in its memory.
"CASPER" functions include storing and averaging the measurements acquired, printing the results (through IR
communication interface) and connecting to the computer for filing the data, using a USB connection.
The memory can store 300 complete analyses and the data downloaded onto a PC by means of dedicated SW
and a mini-USB serial communication cable. It is also interesting to note that "CASPER" has just one "Li-Ion"
rechargeable battery pack used for powering the instrument; it also has a luminous and large (70 x 38 mm) LC
display boasting excellent readability thanks to its backlighting and also to the zoom function.
Another characteristic that distinguishes it from other similar products in the market is the fact the power supply
that comes with the product can carry out the dual function of battery charger and power supply for the
instrument which means the user can carry out analyses even if the batteries are completely flat.
As far as concerns maintenance, it is useful to know that the user can replace the sensors himself without having
to send the instrument back to the technical assistance centre: in fact, the sensors are pre-calibrated and
interchangeable.

CASPER is a portable flue gas analyser that was meticulously designed to meet statutory requirements and
specific customer demands. It may be provided in a rugged ABS carry case or waterproof shoulder bag.
The instrument contains one single board with all the basic circuitry, pre-calibrated measuring cells, sampling
pump, silicone keypad, backlit graphic LC display, high-capacity rechargeable Li-Ion battery pack. The two
halves of the case are firmly secured by six screws on the rear of the instrument.
The pneumatic path and measuring cells inclusive of electronic micromodule are located on the back side of the
plastic case and are easily accessed for maintenance and replacement by removing the back lid.
On the instrument lower side are located the pneumatic connectors for the gas probe and for the pressure/draft
measurement, the connector for the gas probe thermocouple plug and the 8 poles mini- IN connector for the
combustion air probe.
On the instrument left side are located the connector for the external power supply and the mini USB one.
The user interface consists of a constantly active backlit graphic LC display and silicone keypad. Menu screens
and all user messages can be set in the language of the country where it is used; this can be selected through
the menu in one of the available ones. Use of the analyser is simplified by symbol keys that give direct access to
main instrument functions. Shifting between the various menu screens is easy and user-friendly thanks to four
cursor keys, an ' ' key and ' ' key.
