ST-50 NEW electronic
HYGROTHERMOGRAPH
measures, shows and records without computer


The ST-50 is a self-contained, compact temperature and humidity recorder. It records the changes of both parameters on chart paper while the built-in large display indicates both real time values.
Highly accurate electronic sensors guarantee reliable measurements over a long period of time. Remote monitoring up to 50 meters with optional cable is possible.
Long term recording (up to six months), durable fibre tipped pens, battery and AC adapter power supply, user-selectable recording ranges and chart speed make the ST-50 the most complete hygro-thermograph available on the market at a reasonable price.
Applications are in pharmaceutical, semi-conductor, food processing, chemical, electronic industry, in production and quality controls, building and facility administration, field monitoring, labs and clean room, storage control, agriculture, livestock, museums and fine arts galleries, HVAC. The ST-50, whose accuracy control is based on established traceability, is qualified for authorization under ISO 9000 standards.
Features:
  • Compact and lightweight, made with corrosion-proof materials.
  • Desktop and wall mounting.
  • Fast and accurate response, programmable alarms.
  • Long-term recording up to six months.
  • On-chart recording and digital read-out with useful extra indications.
  • Easy access to the chart paper through the transparent front.
  • Programming by built-in, easy to access switches.
  • No computer is needed.
