Environmental Instruments

They develop and manufacture products and services for environmental and industrial measurement.

Vaisala – Environmental and Industrial Systems

Vaisala’s origins date back to the 1930’s when Professor Vilho Väisälä, Vaisala’s founder and long-time managing director, invented some of the operating principles of a radiosonde. He sent the first Finnish radiosonde aloft in December 1931….History – Vaisala

Model 1056 Intelligent Dual Input Analyzer

Model 1056 Intelligent Dual Input Analyzer

This multi­parameter instrument offers a wide range of measurement choices supporting most industrial, commercial, and municipal applications. The modular design allows signal input boards to be field replaced making configuration changes easy.

  • HART and Profibus DP digital communications are available..
  • The Model 1056 accepts single or dual sensor input.
  • Inputs are isolated from other signal sources and earth ground.
  • Two 4­-20 mA or 0­-20 mA current outputs are electrically isolated.

Electronic instruments for the measuring of the following parameters: Temperature, Relative Humidity, Pressure, Light, Acoustics, pH, Conductivity, Dissolved Oxygen and Wind speed.

Delta OHM – Process and Environmental Instruments

The HD2106.1 and HD2106.2 are portable instruments with a large LCD display They measure conductivity, liquid resistivity, total dissolved solids (TDS) and salin ity using combined 4-ring and 2-ring conductivity/temperature probes. Temperature only is measured by Pt100 or Pt1000 immersion, penetration or contact probes.
