These rays are filtered partially by the ozone layer, but some still reach the Earths surface. Immediate or 1s, 5s, 10s, 15s, 30s, 1min, 2min,Ĥ 1. UVB UVB rays have slightly longer wavelengths (280-315 nm) and lower energy than UVC rays. LP 471 probes for the measure of UV IRRADIANCE Other functions include: the relative measurement REL, the HOLD function. The Max, Min and Average functions calculate the maximum, minimum and average values. Both versions of the instrument HD2102.1 and HD2102.2 are fitted with an RS232C serial port and can transfer data in real time to a PC or a printer. The measurment interval, printing, and baud rate are configured with key pad. Data can be transferred from the instrument connected to a PC via the RS232C serial port or USB 2.0 port. Up to 38,000 samples with single probes and 14,000 with combined probes can be stored in local memory. The HD2102.2 Version includes datalogging. In addition to spot measurement the instrument can also integrate measurements for a time integral Q(t) over preset thresholds. Ultraviolet B (UVB) has a shorter wavelength and is associated with skin burning. When the probe is attached to the meter the meter can read the chip to identify the probe and is instantly ready to proceed with measurements. Two types of UV light are proven to contribute to the risk for skin cancer: Ultraviolet A (UVA) has a longer wavelength, and is associated with skin aging. The unit works with "intelligent" probes using the SICRAM automatic detection system which is chip contaning all the parameters of a given probe including calibration data. They measure illumination, luminance, PAR (Photosynthetically Active Radiation) and irradiance (across VIS-NIR, UVA, UVB and UVC spectral regions or in the measurement of effective irradiance according to the UV action curve). Another problem is that you can’t control the exposure of your skin to these good rays. The Delta-Ohm HD2102.1 and HD2102.2 are portable photo radiometers. UVB rays can’t be very beneficial for your skin in the sunlight, because UVA and UVC rays are also presented there at the same time. This is page features the UV photometer versions of the instrument Software included for download and display.The Reptisun® UVB/LED bulb emits UVB wavelengths from 295 nm to 320 nm. ![]() However, only some UVB wavelengths (from 290-315 nm) help synthesize Vitamin D3. Real time data logging to PC or printer UVB wavelengths along with proper temperature (usually additional heat), are responsible for vitamin D3 production in reptiles.
