The Portable III was designed to be the smallest, lightest and fastest 386 machine, since Compaq was under the pressure from Toshiba with its T1100 and T3100 and Zenith Data Systems with its Z-181. Compaq only had 286 motherboards ready for mass production, so the 386 version, the Compaq Portable 386 , would follow about one year later.
TGOR – total gas oil ratio (GOR uncorrected for gas lift gas present in the production fluid [citation needed]) TH – tubing hanger; THCP – tubing hanger crown plug; Thr/Th# – thruster ('#'- means identification letter/number of the equipment, e.g. thr3 or thr#3 means "thruster no. 3" [citation needed]) THD – tubing head; THERM ...
The photoionization detector is an efficient and inexpensive detector for many gas and vapor analytes. PIDs produce instantaneous readings, operate continuously, and are commonly used as detectors for gas chromatography or as hand-held portable instruments. Hand-held, battery-operated versions are widely used in military, industrial, and ...
Greenhouse gas monitoring is the direct measurement of greenhouse gas emissions and levels. There are several different methods of measuring carbon dioxide concentrations in the atmosphere, including infrared analyzing and manometry. Methane and nitrous oxide are measured by other instruments.
An electronic circuit containing a feedback loop controls the gas-pump current to keep the output of the electrochemical cell constant, so that the pump current directly indicates the oxygen content of the exhaust gas. This sensor eliminates the lean–rich cycling inherent in narrow-band sensors, allowing the control unit to adjust the fuel ...
A monitor that checks that the encoder is working properly. The wearable Portable People Meter carried by each panelist. A base station for each PPM, where each panelist in the household places it overnight to recharge the battery. A portable charger for vacations and other trips away from the home base.
