ADC Summit is designed for users that moves both horizontally and vertically since the product has a built-in altimeter,
says Christer Svensson, product manager at Silva. Examples of users are mountaineers, trekkers, skiers etc.ADC Summit is
also equipped with a barometer and works as a weather station with continuous weather forecasts. For the alpine skiers
there is a ski-run count function which counts the numbers of runs as well as the accumulative descend. All functions in
the ADC Wind can be connected to alarms to alert the user. The ADC Summit has a data log memory of almost 2000 readings,
which can be downloaded to a PC through the Infra Red port to visualize the activities/data graphically. For this the
optional accessory ADC IR is needed

Atmospheric Data Center
Measuring all kinds of atmospheric data such as wind, temperature, altitude, barometric pressure and humidity is both a matter of interest but can, in different applications, being absolutely essential for different users. The ADC series (ADC Wind, ADC Summit and ADC Pro) are all specially constructed to meet the high demands of measuring the elements for different user. Bring one the next time you prefer knowledge to guesses!

This is the top model in the ADC line. Having all the features the ADC Summit has and adding the humidity sensor, this is the unit for the professional/mostdemanding users. The humidity sensor provides information such as RH (relative humidity), heat index, air density/relative air density, dew point, wet bulb - all functions for professional users such as engineers, painters, engine tuning as well as for the hobbymeteorologists, the mountaineers and demanding outdoor users.

With the mechanical battery-free THOMMEN Altitrek altimeter plus barometer, it is possible to read the existing altitude during outdoor activities, but also to determine height difference, absolute atmospheric pressure (QFE) and the reduced atmospheric pressure at sea level (QFH).
These functions and information are an invaluable orientation tool to realize an imminent weather change in alpine areas.

Altitude measuring range 0 ÷ 5000m, Resolution 20m, Error limit ±30m, Barometer scale 670 1060hPa (mBar), Operative range -45 ÷ +85 °C, Dimension 64x68x20mm, Weight 70g

The THOMMEN PARAMASTER is a mechanical altimeter for parachuting and has been developed in cooperation with leading Swiss skydivers and armed forces. Particular attention has been given to extreme high reading accuracy. These characteristics combined with the easy handling, great shock-resistance and battery-free operation guarantees the necessary and essential safety.

Altitude measuring range 0 ÷ 4000m, Resolution 50m o 100m, Error limit ±50m.

With the mechanical battery-free THOMMEN Classic altimeter plus barometer, it is possible to read the existing altitude during outdoor activities, but also to determine height difference, absolute atmospheric pressure (QFE) and the reduced atmospheric pressure at sea level (QFH).
These functions and information are an invaluable orientation tool to realize an imminent weather change in alpine areas. Each THOMMEN Classic works with a temperature compensated and calibrated mechanism.

The THOMMEN NIGHTWING was developed specifically for night HALO/HAHO parachute operations. The integral illumination system is based on the one used in our aviation instruments. Four red-light sources illuminate the display face with soft, even, diffuse lighting. As with all Thommen altimeters the utmost emphasis is placed upon reliability, ease of use, error-free readability, and perfect accuracy. Qualified for jumps into water.
