Our Best Selling PAR Meter, The Apogee MQ 500 Bundled with Telescopic Wand, Accurate for LED, Rugged, Lightweight, 4 Year Warranty

 Ean: 0887437032626   |    PartNumber: ApogeeMQ500-AM310Bundle   |   Asin: B07M9FZFJY

MQ500 bundled with Apogee telescoping wand: The MQ-500 has a hand-held meter, attached via cable, that displays and stores measurements. The sensor incorporates a blue-enhanced silicon photodiode and custom optical filters with a rugged, self-cleaning sensor housing design, anodized aluminum body with acrylic diffuser. Typical applications include PPFD measurement over plant canopies in outdoor environments, greenhouses, and growth chambers, and reflected or under-canopy (transmitted) PPFD measurements in the same environments. Quantum sensors are also used to measure PAR/PPFD in aquatic environments, including salt water aquariums where corals are grown. The meter has a sample and log mode, and will record an integrated daily total in mol m-2 d-1. Sample mode will record up to 99 manual measurements. Log mode will power the meter on/off to make a measurement every 30 seconds. Every 30 minutes the meter will average the sixty 30 second measurements and record the averaged value to memory. The meter can store up to 99 averages, once full it will start to overwrite the oldest measurement with new ones. An integrated daily total will be recorded from the 48 averaged measurements (making a 24 hr period). Sample and log measurements can be reviewed on the LCD display or by downloading the data to a computer, however, the integrated daily total can only be viewed by downloading the data to a computer. Downloading data to a computer requires the AC-100 communication cable (a standard USB cable will not work) and ApogeeAMS software.

Solarmeter Model 6.5R Reptile UV Index Meter, ABS Polymer, Black

Model: Solarmeter Model 6.5R   |    Mpn: Solarmeter Model 6.5R   |    Ean: 0713049549293   |    PartNumber: Solarmeter Model 6.5R   |   Asin: B076GXJFJG

Solarmeter s new Model 6.5R Reptile UV Index Meter updates our legendary original Model 6.5 UV Index Meter with attractive, informative graphics specifically designed for reptile husbandry. Many scientists and breeders worldwide rely on the original Model 6.5 UV Index Meter, so the new Model 6.5R is unchanged operationally or in terms of specifications from the original. We just made this meter easier for reptile owners to use by updating the graphics with the latest scientific research about proper UV dosages for reptiles. Specifically, the Ferguson Zone chart at the top of the meter provides the user with an instant, accurate reference for the meter s UVI readout. To operate, press and hold push-button switch on face of unit. Aim sensor window in top panel of meter directly at UV source. Note reading on LCD and record if desired. Battery operation voltage is 9V down to 6.5V. Below 6.5V the LCD numbers will begin to dim, indicating the need for battery replacement. Under "typical" service load, the battery should last approximately 2 years.

Features

  • High Accuracy Measurement of Erythemally Effective UV Light Weighted to Match Vitamin-D Action Spectrum in Reptiles
