ES-642

Met One Instruments’ remote dust monitor the ES-642 is a type of nephelometer which automatically measures real-time airborne PM10, PM2.5, or TSP particulate concentration levels using the principle of forward laser light scatter.

An industrial air quality sensor designed to provide accurate measurements of particle concentration in both indoor and outdoor environments. It includes an LCD display to provide information about particulate concentration, flow rate, instrument status and power.

Sample air is drawn into the ES-642 and through the laser optical module, where the particulate in the sample air stream scatters the laser light through reflective and refractive properties. This scattered light is collected onto a photodiode detector at a near-forward angle, and the resulting electronic signal is processed to determine a continuous, real-time measurement of airborne particulate mass concentrations.

Applications include:
• Rail and roadside monitoring
• Schools and playgrounds
• Underground facilities
• Solar power installations
• Wind energy installations
• Farms and ranches
• Hotels and public venues

Also, the ES-642 is installed with other particulate monitors such as the BAM and FRM instruments.

SV 85

The SV 85 is a ICP® based TRI-AXIAL ACCELEROMETER designed for general purpose vibration measurements with the SVAN 958A four-channel analyser. The HERMETIC SEALED tri-axial industrial piezoelectric accelerometer is suitable to monitor the vibration in harsh industrial environment. The signal ground is ISOLATED from the mounting surface and outer case to prevent ground loops

SA 279

The SA 279 outdoor kit protects the SVAN 979 preamplifier and microphone from the weather conditions. The use of the outdoor kit requires the extension cable between the instrument and its preamplifier. The SA 279 is made of lightweight materials and is easy to install on a tripod. The solution is recommended for short term and semi-permanent noise measurements in the environment.

 

SA 277

The SA 277 outdoor kit protects the SVAN 977 preamplifier and microphone from the weather conditions. The use of the outdoor kit requires the extension cable between the instrument and its preamplifier. The SA 277 is made of lightweight materials and is easy to install on a tripod. The solution is recommended in short term and semi-permanent noise measurements in the environment.

 

SA 271

The SA 271 outdoor kit protects the SVAN 971 pre-amplifier and microphone from the weather conditions. The use of the outdoor kit requires the extension cable between the instrument and its pre-amplifier. The SA 271 is made of lightweight materials and is easy to install on a tripod. The solution is recommended in short term and semi-permanent noise measurements in the environment.

 

 

 

SV 279 PRO

SV 279 PRO is an outdoor monitoring system based on SVAN 979 Class 1 sound level meter. The IP 65-rated case contains a lead-acid battery which operating time can be easily extended by connecting an external battery or solar panel. The intelligent charging unit enables use of a solar panel without expensive controllers and heavy batteries. The case is fitted with very robust, waterproof connectors (military standard) and is supplied with an IP 65 external power supply.
The light-weight outdoor microphone kit can be easily installed on a mast with standard mounting threads. All accessories fit conveniently into a second carrying case. The system provides broad-band results such as Leq, Max, Min and Peak with all standard weighting filters together with an incredible time-history logging feature with two adjustable logging steps.
The broad-band results can be recorded in three acoustic profiles which enable measurements to be taken with 3 different filters (e.g. A, C, Z) as well as 3 different detector time constants (e.g. Fast, Slow, Impulse). The SVAN 979 can be easily removed from the case and used as a hand-held sound level meter.
The monitoring station uses the 3G modem for the remote communication with Internet. SvanNET, the relay server, supports the connection between PC and station.
The SvanNET allows the usage of the system with all types of SIM cards, regardless if they have public or private IP. Additionally, it gives an access to a status of monitoring stations over a mobile phone or tablet.

SV 271 LITE

SV 271 LITE is an outdoor monitoring system based on type approved SVAN 971 Class 1 sound level meter. The IP 65-rated case contains a lead-acid battery which operating life can be easily extended by connecting an external battery or a solar panel. The intelligent charging unit enables use of a solar panel without expensive controllers or heavy batteries. The case is fitted with very robust, waterproof connectors (military standard) and is supplied with an IP 65 external power supply.

SV 307

The SV 307 is a new Noise Monitoring Station dedicated for permanent noise monitoring. The SV 307 integrates Class 1 sound level meter with a modem in the removable waterproof housing. The SV 307 is equipped with a new MEMS microphone with a life-time warranty. The measurement data is stored on the microSD card.

The SV 307 is designed for permanent noise monitoring, it has been equipped with a patented double self-system check: an inbuilt reference sound source producing 100dB at 1 kHz plus real-time check based on reference microphone.

The waterproof housing of SV307 can be removed to get an access to the user interface with a colour display and keypad. The SV 307 has an internal Li-Ion battery and interface for connecting solar panels.
