radiometer photometerGigahertz-Optik’s hand-held P-9710-4 radiometer photometer features an external TTL trigger input function for remote timing of pulsed light measurements. In the P-9710-4 pulse energy mode, the measurement begins automatically upon the trigger input. The meter is capable of measuring the pulse energy (Joules, J/cm2, lux-seconds, effective candela) of single and multiple burst pulsed events >1 microsecond in length. Stepped auto-ranging allows the user to zoom-in on the correct gain level with the last setting stored for future use. Independent of signal magnitude, system bandwidth is 0.166 Hz (at 6s) to > 300 MHz within the unit’s current measurement range of 0.1 pA to 2 mA. Fifteen other menu selectable modes of operation including CW, dose, RS232 remote control plus internal datalogger function and AC or rechargeable battery power qualify the compact P-9710-4 for laboratory or field use. Other key features include adjustable sampling time (100 micros to 6 s) and continuous offset of the pre-trigger light level as well as computation of luminous effective intensity based on selectable standard methods.
