Daily Rate: £34.00

Minimum hire: 4 days

A two-channel version of our favourite Type 2250-E Sound Level Meter with all the same application possibilities plus some added capabilities:

Sound Intensity (the only instrument for this application)
2 Channel Logging/ Building Acoustics/ Frequency Analysis
On board camera

The large screen is touch sensitive and the user-interface is really intuitive with context-sensitive on-screen help in case you get stuck (of course the included quick guide should also help). There is a single ‘traffic light’ button to control the measurement so it’s as simple as start, stop, store.

Either of its ‘stable-mates’, Type 2250-E or Type 2250-L share a lot of functionality and so may be worth considering for all but the most specialised applications.

Two independent measurement channels support applications where simultaneous measurement of two signals is required, such as Sound Intensity. This also allows Type 2270 to measure two transducers simultaneously, which halves measurement time for applications requiring multi-point measurement.

Consequently, applications like façade insulation measurements that use traffic noise as the sound source can be performed with Type 2270 alone, and don't need two sound level meters.

Overview of Features:

Broadband parameters with simultaneous time and frequency weightings in two channels
Seven Statistical parameters including L90, L10 etc
Octave or 1/3 Octave Frequency Analysis
Logging of all the above to produce time-history reports
Compatible with our range of Environmental Enclosures, Outdoor Microphones and Remote Communication options
Audio recording –event triggered (on threshold exceedance), for the complete measurement or manually controlled (requires remote communication)
Single range setting up to 140dB
3 Hz to 20 kHz broadband linear frequency range with supplied microphone Type 4189/4190
16.4 dB to 140 dB A-weighted dynamic range with supplied microphone Type 4189/4190
Communication via USB, LAN, or GPRS/3G modems
USB 2.0 host for connection to printer, GPS, weather station, modem
USB interface (plus Ethernet port on G4 instruments) – for data download and remote control
Plug-in rechargeable Li-ion battery (> 8h operation) + mains power supply
SD memory slot (two on the G4 instruments) that support Secure Digital High Capacity (SDHC) cards
Integrated camera - pictures are an integral part of the measurement in some applications, such as for sound mapping in the Sound Intensity application module

If your measurements require some advanced analysis or specialist functionality, there are a range of additional software modules available, including:

BZ7225 Enhanced Logging
BZ7228 Building Acoustics
BZ7230 FFT Analysis
BZ7231 Tone Analysis (often used with BZ7230)
BZ7223 (Sound Intensity)

Sound Intensity Measurements

Type 2270-G system includes BZ7233 Sound Intensity software + 3654 SI Probe which makes for a portable and easy to operate SI measurement system.
