Manometer displays gauge and differential pressure\/vacuum in eleven different units. Response time is 0.5 second. Simple hose fittings on the unit permit using hose\/tubing with inside diameters from 1\/16 to 3\/16 inches. Large 5\/8-inch-high digits are visible from six feet. At the touch of a button unit may be zeroed or any pressure may set to zero. Differential feature permits reading the difference of the pressure or vacuum between two different sources. Memory feature recalls highest and lowest reading over any time period. A count up timer displays up to 99 hours, 59 minutes, 59 seconds. A DATA HOLD key freezes the display to capture readings. Brilliant backlighting permits reading even in dark areas. Computer output permits all units to be connected to a computer for monitoring and storing results. Accuracy is ±0.3% of full scale between 0 to 50°C. To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). Printing Model Data logging feature permits automatically capturing and storing up to 12,000 readings, including date and time, at intervals as short 1 second or as long as 2 hours. Printing model allows the user to manually capture and store up to 99 readings, including date and time at the press of a button. Printer provides a hard copy for today's stringent quality-control documentation. Printer model prints samples number, current reading, date, and time. Printer allows both manual memories and data logger memories to be printed without the need for a computer. Computer output allows manual memories, data logger memories, and current programmable capturing to be streamed to a pc computer. Printing\/data logging model is supplied with Traceable® Certificate, hose\/tubing, AA batteries, ABS plastic carrying case, computer output, 79-inch computer cable with software on a CD and paper roll. Size is 2-3\/4 x 8 x 1-3\/4 inches and weight is 12 ounces. Replacement battery Cat. No. 1111 (4 each). Non-Printing model Non-printing model is supplied with Traceable® Certificate, hose\/tubing, 9-volt battery, computer output, and ABS plastic carrying case. Computer output allows current programmable capturing to be streamed to a pc computer (computer cable and software not supplied, requires accessory 8045). Size is 2-3\/4 x 7-1\/8 x 1-1\/8 inches and weight is 5 ounces. Replacement battery Cat. No. 1112.
