Sound Level Meter – Type 1 & 2
Do you need an all-in-one solution for your noise measurements? The Cirrus CR172B Optimus Green gives you all the noise data you could possibly need for both environmental and occupational noise.
By measuring every parameter you need simultaneously, the Optimus Green records everything in one measurement. There’s no risk of choosing the wrong function or missing any data. All you need to do to get going is switch on, calibrate and start. It’s that simple.
All of your measurement data displays on the large OLED screen. You’ll be able to see instantly if there are any noise issues that need further investigation. You can easily navigate screens during measurements to see the data you need.
Whether it’s environmental noise monitoring, detailed noise analysis using audio recording or workplace noise measurements, the Optimus Green has you covered.

Outdoor Noise Measurement Kit – Type 1 & 2
The CK:680 is a weather protected outdoor kit that is designed for use with the optimus green sound level meters. The kit allows the optimus to be used outdoors over long periods of time and in all weather conditions.
The kit has been designed to allow the measurements from the sound level meter to be downloaded directly into the NoiseTools software over a 3G/GPRS connection. This type of connection removes the need for a modem at the host PC and allows data to be securely transmitted over the internet.
When the kit is connected to NoiseTools, the instrument appears as if it was connected directly using the USB connection. This allows every function and feature of the optimus to be accessed remotely.
- Fully weather protected outdoor noise measurement kit
- Remote download of measurement data over 3G/GPRS connection
- GPS location data stored with each measurement
- Automatic synchronisation of the instrument clock to the GPS time signal
- Live alerts via Email, SMS or Twitter when an Acoustic Fingerprint template is activated
- Provides weather protection for an optimus green sound level meter & microphone
- Battery power for 6 days operation with one standard battery pack (supplied)
- Additional battery pack provides an additional 6 days power for up to 12 days operation
- External power connection for longer operation
- Secure lockable case with space for all standard instrument accessories
- Standard 10m microphone cable
- Optional microphone extension cables up to 100m
- Optional tripod available
The kit consists of a weatherproof case (CK:602) and an outdoor microphone (MK:170).
Environmental Noise Logger Kit
SVAN 958A Class 1 Four-channel Sound & Vibration Analyser is dedicated for all applications that require simultaneous class 1 sound and vibration assessment. Each of the four input channels can be independently configured for sound or vibration detection with different filters and RMS detector time constants giving users an enormous measurement flexibility. The real advantage of SVAN 958A is the capability to perform advanced analysis simultaneously to the level meter mode. In practise this allows the user to obtain broad-band results such as Leq, RMS, LMax, LMin, LPeak together with four-channel analysis like FFT or octave band analysis.
List of available analyser functions includes FFT, 1/1 or 1/3 octave, cross spectra, sound intensity, RT 60 and more. The 4-channel time-domain signal recording to .wav format is available as well as an exceptional feature! All measurement results are stored in non-volatile 32 MB internal memory or USB memory stick and can be easily downloaded to a PC with SvanPC++ software. SVAN 958A with RS 232 interface (SV 55) can be offered with GPRS modem or LAN & WLAN connection module. Together with SvanPC++_RC (remote communication) software, these interfaces provide easy remote access to instrument settings & data over Internet and local area network. Instrument is powered from four AA standard or rechargeable batteries as well as from the external DC power source or USB interface. Robust case and light weight design accomplish the exceptional features of this new generation instrument.
The doseBadge noise dosimeter system is the perfect solution for measuring a worker’s noise dose exposure. The badge is small and light, with no cable or controls and mounts comfortably on the worker’s shoulder. The dosimeter is then left on the worker, storing details about the noise levels throughout the day.
The doseBadge has no controls or display and all control is over the infra-red link to the Reader. The doseBadge case is a lightweight alloy, giving added strength to the already strong cone shape.
The doseBadge contains the microphone, a rechargeable battery and the electronics to acquire and analyse the levels continuously.
- IEC 61252 and ANSI S1.25 to Type 2
- Suitable for ISO, OSHA, MSHA, AICHE and ACGIH noise applications
- Intrinsically Safe version available
- No wires or controls on the badge to catch or knock
- Very rugged cast aluminum case
- Powered by a rechargeable battery
- Time History gives a graph of noise levels
- Noise measurement span from 70 to 130 dB(A)
- True Peak reading from 120 to 140 dB(C)
