The Laboratory Environment Monitor (LEM) provides the ability to measure barometric pressure, ambient temperature, relative humidity and air density. The LEM transmits these measurements via an RS-232 or RS-485 interface to a PC. The supplied software can then be used to monitor and log all the above parameters for one or up to eight LEMs, simultaneously.
The supplied software allows the LEM to be used as a stand alone instrument and performs a variety of functions, including various units selection, as well as as well as data logging. The LEM is an ideal replacement to older data loggers, such as mechanical strip chart recorders. The software includes options for logging in intervals of one minute, five minutes or 15 minutes. The space delimited text file keeps file sizes small, while allowing easy insertion into spreadsheet applications for data analysis and graphing. The LEM also provides air density measurement— a critical factor for mass calibration labs to correct for air buoyancy effects.
Annual recalibration of the LEM is accomplished through the supplied software. Once calibrated, the new coefficients are downloaded to the LEM and stored in non-volatile memory.
If a barometric pressure accuracy better than 0.04 inHg (1.3 mbar) is required, a variety of digital barometers with an RS-232 interface can be directly connected to the LEM. The LEM will transmit the barometric pressure reading from the external barometer to the PC and LEM software via a single communication link.
The LEM is compatible with a Ruska Model 2456 piston gauge monitor and WinPrompt® software, which automates the operation of the extensive line of Ruska primary pressure standards. The LEM allows WinPrompt to automatically compensate for air buoyancy effects on the mass set of the piston gauge. The LEM is also compatible with the Model 2465 autofloat gas piston gauge.
