HF scientific AccUView LED Online UV Transmittance Absorbance Analyzer with Flow Alarm, 28042
Description
- Continuously measures UV transmittance or absorbance
- Long-life LED light source and minimal maintenance
- Automatic ultrasonic self-cleaning measuring chamber
Use the AccUView LED online UV analyzer to take continuous measurements of UV transmittance or absorbance in your drinking water disinfection system. Compact and easy to use, it features an all-in-one design that needs minimal maintenance—making it the most cost-efficient instrument of its kind.
Analyzer uses advanced LED technology to take 1-second measurements during a user-programmable interval (4 to 60 seconds). This extends service life—it's typically 10 years before you need to replace the LED lamp. Analyzer features two independently programmable relay outputs and a 4-20 mA analog output. Features an integral flow alarm switch that sends notifications if inlet flow drops below 1 L/min.
Calibration is simple using a single reusable calibration standard; calibrate weekly for optimum accuracy. Simply fill a cuvette with calibration solution, place it into the measuring chamber and verify the reading—just like a laboratory meter! The cuvette holds just 25 mL to reduce calibration costs. Desiccant and internal heating systems control the measuring environment, eliminating condensation to give you worry-free, reliable readings.
A patented autoclean system keeps the optical glass cuvette chamber clean by sending an ultrasonic frequency through a unique device bonded to the bottom of the cuvette. This convenient feature keeps the glass from staining and lengthens the time between necessary manual cleanings and maintenance. To make periodic maintenance easier, order the tubing replacement kit (stock # 41394), which contains a shutoff clamp, backpressure valve, and 5/16"-OD black tubes with fittings for the analyzer's flow-through assembly. Approvals: CE, UL, CSA.
Analyzer includes: desiccant pouch, two auto-cleaning optical glass cuvettes, field power supply box with interconnecting cable, backpressure valve, inlet pressure regulator, and 125-mL bottle of 100% calibration standard.
- Range: 0 to 100% transmission, 0 to 2.0 ABS
- Accuracy: ± 1.0%T, ±0.002 ABS
- Resolution: ± 0.1%T, ±0.0001 ABS
- Outputs:
⚬ Analog: 4-20 mA (when RS-485 not in use)
⚬ Relays: two SPDT, programmable for hi/low/error alarms (with delay); rated 2A @ 120 VAC - Operating conditions: 32 to 122°F
- Flow rate: 0.026 to 0.40 gal/min (100 mL/min to 1.5 L/min)
- Inlet water pressure: max 200 psi (integral pressure regulator)
- Power: 100 to 240 VAC, 47 to 63 Hz
- Dimensions: approx. 9"W x 15.5"H x 8"D
- Communication: RS-485 Modbus (when 4-20 mA not in use)
