Optical metrology equipment for climatologists and meteorologists
The laser ceilometer from JENOPTIK Laser, Optik, Systeme GmbH measures such atmospheric parameters as cloud height, visibility and the height of a planetary boundary layer. The product provides the first ever metrological device to safely detect also cloud layers and cirrus clouds at height levels up to 15 kilometers. This marks a major progress in the science of meteorological and climatologic forecasting. Measurement is accomplished with an opto-electronic laser sensor that relies on the LIDAR principle, an optical version of radar: A solid-state laser emits light pulses into the atmosphere. The light which is scattered by air and aerosol molecules is collected with a specific optical setup to be detected by a highly sensitive photo receiver (APD). By analyzing the pulse transit time and the intensity of backscattered light portions, smart algorithms compute a high-resolution aerosol height profile along with other related measurement readings. With integrated heating and cooling functionality and designed for autonomous operation, the CHM 15k can be relied to perform in any weather conditions.

Red Lion is pleased to announce the release of a second meter in our new series of PAX® Lite panel meters featuring setpoint control, the PAXLCR. This meter features two independent counters and separate rate display capability. Easy PAX style programming makes meter set-up quick and simple. In addition, the PAXLCR provides dual setpoint control allowing users to have upper and lower control limits via two 5 Amp Form C relays.
The meter has two signal inputs and a choice of eight different count modes. These include bi-directional, quadrature and anti-coincidence counting, as well as a dual counter mode. When programmed as a dual counter, each counter has separate scaling and decimal point selection.
Rate indication is available in all count modes. The rate indicator has separate scaling and decimal point selection, along with programmable display update times. In addition to the signal inputs, the user input can be programmed to perform a variety of meter control functions.
The dual setpoint outputs can activate based on either counter or rate setpoint values. An internal batch counter can be used to count setpoint output activations.
* 6 Digit, 0.56" High Red LED Display
* Programmable Scaling for Count and Rate
* Bi-directional Counting, Up/down Control
* Quadrature Sensing (up to 4 Times Resolution)
* Built-in Batch Counting Capability

A gamma ray interacting with a scintillator produces a pulse of light that is converted to an electric pulse by a photomultiplier tube (PMT). The PMT consists of a photocathode, a focusing electrode, and 10 or more dynodes that multiply the number of electrons striking at each dynode. A chain of resistors typically located in a plug-in tube base assembly biases the anode and dynodes. Complete assemblies including the scintillator and PMT are available.
The properties of a scintillation material required to produce a good detector are transparency, availability in large size, and large light output proportional to gamma-ray energy. Few materials have good properties for detectors. Thallium-activated sodium iodide [NaI(Tl)] and cesium iodide [CsI(Tl)] crystals are commonly used, as well as a wide variety of plastics. CsI(Tl) and plastics have much faster light decay times than NaI(Tl) and are primarily used for timing applications.
The high Z of iodine in NaI(Tl) crystals result in high efficiency for gamma-ray detection. Resolution for a 3-inch diameter by 3-inch length crystal is typically about 7% for 137Cs and slightly worse for larger sizes. The light decay time constant for a NaI(Tl) crystal is about 0.23 µs. Typical charge-sensitive preamplifiers translate this into an output voltage pulse with a rise-time of about 0.5 µs. Fast coincidence measurements cannot achieve the very short resolving times that are possible for plastic scintillators, especially at low gamma-ray energies.
