1. Both the ATC 140 and ATC 250 feature a dual zone heating technology Each heating zone is independently controlled for precision temperature calibration The homogeneity in the lower part is close to that of a laboratory liquid bath The lower zone ensures optimum heat dissipation throughout the entire calibration zone The upper zone compensates for heat loss from the sensor under test and from the open top This design also eliminates the need for insulation of the sensors under test and makes it possible to calibrate liquid filled and other mechanical sensors Sensor under lest fee eet UC i Sii a aa TT 1 EF a f fa LI pe Up Py rea a a aa ote Pills erature ete See _ Internal reference ATC heating and cooling models The ATC 140 model with both heating and cooling capabilities feature the Peltier element multi stage technology This both improves efficiency and extends the life of the electronic heat pump Peltier effect ATC 140 In 1834 Jean Peltier a French physicist found that an oppo site thermocouple effect could be observed when an elec tric current was connected to a thermocouple Heat would be absorbed at one of the junctions and discharged at the other junction This effect is called the gt PELTIER EFFECT A A Pre The practical Peltier element electronic heating pump consists of many elements of semiconductor material connected elec trically in series2. 36 8 Ib PN S0 M anea aarin 14 6 kg 32 2 Ib Size Lx W x H 570 x 235 x 440 mm 22 4 x 9 3 x 17 3 in Shipping carrying case only Woighi seere eener E eA 6 0 kg 13 2 Ib Size Lx W x H 670 x 309 x 514 mm 26 x 12 2 x 20 2 in Miscellaneous Serial data interface cccccecseeeeeeeeeees RS232 9 pin male Operating temperature 000008 O to 40 C 32 to 104 F Storage temperature cccceee 20 to 500C 4 to 1220F PUCCIO sessen rsa aiei O to 90 RH Protection class sietcevstosceacicaonsenene cunsccneseeieianaasensceoaiarensia IP 10 If a dry block or liquid bath kit is ordered there will be an extra collie of approximately 2 kg 4 4 Ib FUNCTIONAL SPECIFICATIONS Mains specifications ATC 140 250 secccscesssctsesetisconsenas 115V 90 127 230V 180 254 Frequency non US deliveries 50 Hz 5 60 Hz 5 Frequency US deliveries ccccccsseeecssseeeeeeeeseaees 60 Hz 5 Power consumption max ATC 140 cccceeeeeeeees 300 VA Power consumption max ATC 250 csccceeeeseeees 1150 VA Temperature range ATC 140 Maximum Dry DIOCK ccccccesseeeeseeeeeees 140 C 284 F Minimum ambient temp 0 C 32 F 35 C 31 F Minimum ambient temp 23 C 73 F 0 20 C 4 F Minimum ambient temp 40 C 104 F 5 C 23 F ATC 140 Maximum Liquid bath ssssssseeeee
