Own equipment or leased NMT?

You can mix and match your own compatible sound level meter with leased, pre-configured portable NMTs that include all accessories required and come with valid accredited calibration certificates. 1 

When you use your 2250, you supply your own accessories and, importantly, provide internet-communications using for example a router and SIM card. 

With leased NMTs from Brüel & Kjær, all the accessories (outdoor microphone, calibrator, router and SIM card, environmental protection, tripod and security accessories) and the communication costs are included.

When you register your 2250 for use with Noise Sentinel – On Demand, we guide you through a compatibility check and help you set it up. With the leased NMT, this is done for you.

If you use your own 2250, you can start a monitoring the very same day while delivery times for leased NMTs are 3 days. 

Other than that, you use your 2250 and Leased NMTs in exactly the same way. 

By the way, if you need to use equipment with accredited calibration, our Noise Sentinel – On Demand Leased NMT is a very cost-effective alternative.

Note, for users who have little experience of network communication, or wish to have a solution where communication costs for the monitoring period are covered, our Noise Sentinel – On Demand Leased NMT is a very cost-effective alternative to investing in and setting up routers and communication subscriptions.
