CG 842 for routine applications Few keys make this pH meter easy to use, which comes in an attractive design. The relevant data are output on the large multifunctional display (75 × 60 mm). In battery mode, up to 3000 hours of continuous work can be performed without the cumbersome power cord. Alternatively, the optional power supply unit enables power-saving operation at configured measuring station. Calibration can be done using a number of methods with stored DIN, technical and freely selectable buffers. The measuring instrument determines the current state of the measuring chain from the calibration data and symbolically displays this information on the display. A shiftable drift control checks the stability of the measuring signal and ensures reproducibility of the measurement. Technical data: Measurement ranges: pH: -2.000 to +16.000; resolution max. 0.001 mV: -1999.9 to +1999.9; resolution max. 0.1 Temperature: -5 to +99.9°C (man. -20 to +130°C); resolution 0.1 K Calibration: DIN-/Tech. buffers: automatic 2-point calibration Random buffers: conventional 1-/2-point calibration Test stamps: GS, CUL, UL Warranty: 3 years Matching probe for routine precision measurements, e.g.: pH combination electrode type BlueLine 14pH, with integrated temperature probe and fixed cable.
CG 843 with GLP functions Precision pH meter with GLP supporting functions for quick and reliable pH measurements with data storage. The CG 843 provides an ultrahigh level of comfort, reliability and accuracy for all application areas. In addition, the CG 842 has GLP functions, such as calibration protocoling and measurement documentation including date, storage and identification number. The integrated real-time clock issues a reminder for the pending calibration at a given time. The integrated interface with self-detecting output can be used to hook up to a printer, recorder (analog) or PC. CG 843 P with GLP functions and integrated printer Has the same technical data and performance characteristics as the CG 843. The additional, integrated printer enables GLP measurement documentation to be made directly at the workstation. The plug-in power supply unit required for printing comes with the shipment. Technical data: Measurement ranges: pH: -2.000 to +16.000; resolution max. 0.001 mV: -1999.9 to +1999.9; resolution max. 0.1 Temperature: -5 to +99.9°C (man. -20 to +130°C); resolution 0.1 K Calibration: DIN-/Tech. buffers: automatic 2-/3-point calibration Random buffers: conventional 1-/2-point calibration Calibration interval check: 1 to 999 days data memory: 800 data sets Time-ctrld saving: 800 data sets in 7 intervals (5 sec to 60 min) Test stamps: GS, CUL, UL Warranty: 3 years Matching probe for routine precision measurements, e.g.: pH combination electrode type BlueLine 14pH, with integrated temperature probe and fixed cable.
