Thông tin sản phẩm

The JP9710 UV meter is an efficient single-channel instrument designed for multipurpose use in any photometric and radiometric application. In spite of its compact size it offers many high-level features with sixteen different measurement modes. These functions and portability enable the P-9710 to be characterized as both a laboratory grade instrument and a field service meter. A special feature of the P-9710 is its detector head calibration data coupler. All data pertaining to a detector including the model and serial number are stored in the coupler. When connected to the optometer, this data is automatically transmitted and the system is ready to go. This guarantees faultless handling of the instrument when used with any number of different sensing heads. The JP9710's wide measurement range of 0.1 pA to 2 mA covers the dynamic range of most current semiconductor photodiodes for nearly unrestricted use in any light measurement application. The relative accuracy throughout this range is = 0.2 %. Another key feature of the JP9710 is its adjustable integrating time which allows it to function as a fast data logger with a short sampling rate. The JP9710 can measure both instantaneous signal and accumulated energy (dose). The unit's many functional modes of operation are selected using a clearly built-up menu accessed using the front panel buttons. A bi-directional RS232 serial interface al-lows external remote control. Optional Windows based software is available for a quick turn-key solution or user can write his own program using the complete command set supplied. Factory programmed calibration factors can be changed with the OS CAL software. This allows calibration labs and industrial processes employing in-house calibration standards to self calibrate the unit with one or multiple factors.

Features:
CW: Reading (minus any offset) and detector calibration factor is shown on the upper line of the display. The lower line shows the wavelength / identification of the detector. CW Min/Max: Shows the smallest / largest CW value during a measurement period (erased by pressing 'reset' button). Peak Min/Max: Shows the smallest / largest value within the selected measurement time (corresponding to the integration time selected). Peak to Peak: The difference between min. peak and peak max within the selected measurement time (corresponding to the integration time selected). 1- Effective: Evaluation of the effective intensity of pulsed light signals according to the Schmidt-Clausen method. Requires input of the time constant C for daylight observation (0.1 s) and night time observation (0.2 s). Pulse-Energy: Measures the magnitude of single pulses (time integral). Manual or remote-controlled triggering of the time frame adjustable up to a maximum of six seconds. Offset compensation setting of static ambient light. Ratio relative(%): Displays reading in reference to a pre-set value in percent. Attenuation (logarithm): Displays reading in reference to a pre-set or reference value in dB or dBm. Ratio (factor): Displays reading as a factor of a preset value. Hold: Current reading is 'frozen' by pressing 'stop' button. Readings resume by pressing 'run'. CW Level Check: Checks the measured CW value against stored preset lower and upper limit values. Display indicates whether value is within, above or below limits. Useful in remote control applications (RS232) and in combination with the optional I/O relay board. Dose (C): Totals the measured values and displays result as a dose reading. Logger (x): Stores the measured values at preset chronological times (sampling rate). Remote (RS232): Allows remote control of the device using a PC. Default Ini: Resets all parameters to the default condition.

Electrical specifications:
Detector Input-Photocurrent to voltage converter signal input amplifier with 8 gain levels (2.000 mA to 200.0 pA max. gain values). Manual or automatic range switching. 12 bit ADC with up to 14 bits at longer integration times. Detector Connection-Storage of sensor data (serial number, detector model, calibration data) in Eeprom of the detector head coupler. Automatic data transfer when detector is connected to the meter. Calibration factors for detectors with and without accessory can be stored in a table for detectors calibrated over any number of different wavelengths. Manual input and storage of a calibration value into the meter. Storage of up to 12,288 readings. Adjustable sampling rate from 0.1 to 6000 seconds. Manual recording mode. Display of readings stored in the flash EPROMS on the display or on computer using the RS232 interface and software. Power Supply-Battery or AC operation. Built-in rechargeable battery, 6V, 0.5 Ah. Approx. 6 h with display illumination. Battery charge under 8 % is displayed. Operation from AC plug-in power supply (230V/50Hz, other values on request) with specific U/l e-charging characteristic.
