Electronic Humidity Indicator Plugs

Electronic Humidity Indicator Plugs replace traditional humidity indicator papers that rely on a visible colour change, usually from blue to pink, to show humidity changes. The conventional indication range of the paper indicator lies from 10% to 70% relative humidity, and the ambient temperature and tolerance range must be specified. The new electronic humidity uses a polymer humidity sensor combined with a temperature sensor to provide digital display readings of relative humidity, ambient temperature, and dewpoint.

 

Dewpoint shows how the system or instrument can be cooled before condensation (or frost) occurs, qualifying dewpoint as a quality control standard for specific operating performance for both systems and devices. The electronic indicator is mounted in a robust IP67 enclosure with a membrane press switch to activate the three readings in order. Optional thread mounting or bulkhead flange fixing is available. The operational battery life is usually around five years.

 

Stream Peak offers five different models of Electronic Humidity Indicator Plugs:

 

BLD10373 – Electronic Relative Humidity Indicator

Our ERHI Thread 1 1/8″ BSP is the latest innovation, featuring R.H., Temperature, and Dew Point Display in a single unit. The device also allows simultaneous monitoring of the three different readings, which makes it widely applicable. This new electronic relative indicator uses a polymer humidity sensor combined with a temperature sensor to display the three readings digitally. By using the membrane press switch, it activates the readings in sequence. The operating range of the device is between 5% to 90% R.H., -20֯֯°C to 15֯°C dewpoint, -20°C to 60°C temperature and is capable of withstanding a pressure of 80 psi. The recorded data are stored for over six months. The option “data logging” is available under request. The operational battery life is usually around five years.

BLD10374 – Electronic Relative Humidity Indicator

Our ERHI thread M36x2 is the latest innovation, featuring R.H., Temperature, and Dew Point Display in a single unit. It also allows simultaneous monitoring of the three different readings, which makes it widely applicable. This new electronic relative indicator uses a polymer humidity sensor combined with a temperature sensor to display the three readings digitally. By using the membrane press switch, it activates the readings in sequence. With an operational battery life of up to 5 years, the relative humidity indicator also features a range between 5% to 90% R.H., -20°C to 15°C dewpoints, -20°C to 60°C temperature. Also, it is capable of withstanding a pressure of 90 psi. The option “data logging” is available under request, and the recorded data are stored over six months.

BLD10375 – Electronic Relative Humidity Indicator

Our ERHI Bulkhead Mounted is the latest innovation, featuring R.H., Temperature, and Dew Point Display in a single unit. The device also allows simultaneous monitoring of the three different readings, which makes it widely applicable. This new electronic relative indicator uses a polymer humidity sensor combined with a temperature sensor to display the three readings digitally. By using the membrane press switch, it activates the readings in sequence. The operating range of the device is between 5% to 90% R.H., -20°C to 15°C dewpoints, -20°C to 60°C temperature and is capable of withstanding a pressure of 80 psi. The recorded data can be stored for over six months. The option “data logging” is available under request. The operational battery life is usually around five years.

Dewpoint Checker

The Dewpoint Checker allows easy monitoring of the humidity conditions inside the equipment while allowing accurate dewpoint measurements. It is designed mainly for applications necessary to maintain a very low dewpoint, to avoid condensation inside the equipment. Our new Dewpoint Checker uses a polymer humidity sensor combined with a temperature sensor to ensure accurate dewpoint measurements. Two different light colours allow users to monitor the value of the dewpoint when it drops below -25°C and below -40°C. The device also features a third light to provide information about the battery status.

WiFi Temperature and Humidity Data Logging Sensor

Temperature and Humidity Data Logging HDT-WiFi Sensor designed to measure temperature and humidity readings of its surrounding environment, the recorded reading is typically accurate to ±0.3°C / ±0.6°F (5°C to 60°C/41°F to 140°F) and ±2.0% R.H. (20 to 80% R.H. @ 25°C). This logger is ideal for various applications, especially where remote monitoring is essential. These applications include environmental and weather monitoring, agricultural and livestock, food and drink, building and site monitoring, and HVAC. Data can be streamed wirelessly over any WiFi network and viewed on a P.C. using the free EasyLog WiFi software available for download or on the Cloud
