                                    Simco-Ion%u2019s Model 280A incorporates enhanced circuitry that enables it to more accurately measure the performance of high-frequency AC ionizers, as well as Pulse DC ionizers and Steady-state DC ionizers. The architecture of the Model 280A simplifies testing in open or enclosed environments. The detachable plate and programmable automated test sequencing offer remote testing capability, allowing multiple tests without opening an enclosure to reset the instrument. The Model 280A can be used as a portable CPM and is capable for of up to 6 hours of operation on the internal battery before recharge. It has enough memory for storage of over 1000 tests and more than 100 individual test locations.%u2022 Enhanced circuitry bandwidth to measure high frequency AC ionizers%u2022 Improved plate capacitance accuracy%u2022 User programmable test protocol%u2022 Delayed start%u2022 AC line input or battery operation%u2022 Comes with 6%u201d detachable plate%u2022 Built-in temperature and humidity sensors%u2022 Onboard data archiving memory%u2022 Digital LCD display %u2022 Increased dynamic range to capture AC ionization performance%u2022 Provides more accurate decay times%u2022 Manual mode or automated test sequencing %u2022 Portability for easy movement in a variety of test locations %u2022 Ideal for mini-environments and inside process tools%u2022 Accurately documents environmental test conditions%u2022 Onboard memory holds test data with ability to download data for records or analysis%u2022 Easy to read and interpret data screenFeaturesBenefitsModel 280ACharge Plate Monitor280A SpecificationsPower 90-250 VAC, 50/60 Hz, <12W operating(6 hrs internal battery life for portable use; charge time <8 hrs to >90% capacity)Charge PlateDetachable: 6\Capacitance: 20 pF, %u00b15% (not including strays)Zero Drift: <100 mV/sec (no incident ion flow)Self Discharge: <200 mV/secLCD Display 240 x 64 character/graphicDisplay Time (4 digit)Accuracy: 0.1% of reading %u00b11 lsdResolution: 0.1 sec for readings <1000 sec; 1 sec for reading >999 secDisplay Voltage240 x 64 character/graphic; 3.5 digit display (Decay and Peak reading)Accuracy: %u00b10.1% of reading %u00b13 lsd (least significant digit)Resolution: 1V for readings >99V; 0.1V for reading <100VVoltage Peak DetectorBalance Test Bandwidth: <10 Hz (pulse width >50 msec less 10% error typical)Average Voltage Overflo When averaging overflows, the last calculated value for the average voltage will be displayed, and the Avg line of the display will flash, indicating an overflow; the instrument continues to correctly indicate changes to the positive and negative peak voltages, +Vp and -Vp, respectivelyCharge Voltage Range: 10V to 100V above the start voltageResolution: Settable to 1V increments; Accuracy: 0.3% of setting %u00b12.5VStart Voltage Range: %u00b110 to %u00b11000V (1000V, standard)Resolution: Settable to 1V; Accuracy: 0.3% of setting %u00b12.5VStop Voltage Range: 0 to %u00b1995V (1000V, standard)Resolution: Settable to 1V; Accuracy: 0.3% of setting %u00b12.5VElectrometerDynamic Range: %u00b11200VFollower Error: <10 mVSpeed of Response: <10 msec for 1 kV to 0V (90-10%)Bandwidth: -3 db @ 1 Khz 20 Vp-p; 3 db @ 10 Hz 2000 Vp-pNoise: <12 mVrmsSensors Temperature: Range 0-122%u00b0F (0-50%u00b0C), Accuracy %u00b137%u00b0F (%u00b12%u00b0C), typHumidity: Range 10-80% RH @ 25%u00b0C, Accuracy %u00b15%, typMonitor Output Interface: USBAccuracy: Output: 0.1% of reading %u00b112 mV; Impedance: 1 kOhmsOperating Env 41-95%u00b0F (5-35%u00b0C); %u00b15% typ from 10-80% RH @ 77%u00b0F (25%u00b0C)CPM 11 x 9 x 6\Certification105 Sales Service +1 (510) 217-0460 or +1 (800) 367-2452 www.simco-ion.com/technology Instrumentation
