This VWR Digital Conductivity Bench Meter Model 61161-362 is in real good condition and guaranteed to functions 100%. It came from a local lab that was upgrading equipment and we can accept pay pal or your credit card. Please contact me with any questions. Designed to measure conductivity in water analysis, biotechnology, life sciences, environmental studies, and more. Can also be used to check water purity in stills and demineralizers, test laboratory glassware, measure total dissolved solids, and make up solutions. Accurately provides results in conductivity (micromhos/cm and microsiemens/cm), resistivity (megohms), and dissolved solids (parts per million). Large, 4-digit, 12.7mm ( 1/2") LCD shows temperature in degrees C and degrees F. Instant-response probe contains platinum electrodes and a solid-state thermometer for automatic/manual temperature compensation. All readings are referenced to the international standard of 25 degrees C. Computer RS-232 output and recorder jack allows for continuous monitoring and a permanent record. Unit has keys to calibrate to four different calibration points. Chemical-resistant ABS housing withstands harsh environments. Track Page Views With Auctiva's FREE Counter
