The ISOCHECK is a portable automatic processor that, through an “L” or “S” PITOT tube with a “K” thermocouple, allows to easily and immediately measure the pressure and temperature values for further processing. It is equipped with a polycarbonate keyboard to setup the parameters and an alphanumeric LCD display with backlight to display the data. The automatic processor also has a clock to manage DATE and TIME. For continuous measurements is possible to use the data-logger function which allows to store the parameters of pressure and temperature at adjustable time interval, from 10 seconds to 5 minutes. The optional micro valves allow to execute the zero of the sensors with the measure tube insert in the stack without disconnecting the connecting tubes. The instrument feature INDIPENDENT sensors to measure Differential Pressure, Static Pressure, Barometric Pressure and an input for the measure of a type K or J thermocouple. It is available in the certified LAT version (as requested for the ACCREDIA accreditation). Thanks to its capacity to adjust the integration time of the measures it’s possible to execute precise measurement in any flow conditions The dedicated software allows to elaborate the measured parameters and execute the calculation of speed, flow, isokinetic aspiration flow and of the nozzle to use in PM10 an PM2,5 in EMISSION (US EPA METHOD 201A). The calculations are done according the UNI 16911-1 and is possible to insert the SWIRL angle and wall factor (WAF). By the use of its specific menu is also possible to: • calculate the MEASURE and SAMPLING point for circular and rectangular stack according the regulations UNI 16911-1 and UNI 13284-1 • calculate the Density (O2 e CO2) and moisture • execute the LEAK TEST of the Darcy tube • execute the AUTOMATIC ISOKINETIK SAMPLING (optional) with automatic continuous adjustment of the aspiration flow at the change of the fume velocity (it require a sampler of the LIFETEK XP-R series). The data measured and processed can be stored and reviewed lately, they can also be transferred to an USB flash drive or to a PC using the RS232. The processor is powered with internal rechargeable batteries (NiMh) with high capacity with no memory effect which allows long lasting measure time (more than 9 hours).

With the supplied power supply and thanks to its POWER/CHARGE function is possible to use the instrument taking advantage of the mains voltage and correctly charge the internal batteries at the same time. FEATURES UNI EN ISO 16911-1 Dedicated program to execute a leak test of the measure tube (9.3.2 Pre-test leak check) Set of the angle in the measure point; if the angle is greater than 15° the velocity value of the point will be multiplied for the cosine of the angle itself (9.3.5 Swirl or cyclonic flow). For each measure point is calculated the average value for all the parameters (temperature,...
