NHN01 questions
What ranges are available for the NHN01?
Standard coverage is 0–100 ppm. Other spans, outputs, and process connections can be sourced to match the application. Send the working pressure and medium and we will confirm the exact option.
What is the MOQ and lead time?
1 pc (flexible, no minimum for most products). 2-3 days for in-stock items, 15-30 days for custom orders. Samples are available, with freight on the buyer’s account.
Can the NHN01 be customized?
Range, output signal, process connection, cable length customizable through our supply partners.
Do you manufacture this transmitter?
SIBXSUN is an industrial instrumentation supplier in Ningbo, not the factory. We source the NHN01 from qualified partners, inspect before shipment, and handle export documents and logistics.
Need the right ammonia nitrogen sensor for your process?
Send the medium, range, output, and quantity. We will confirm the matching option and a FOB Ningbo quote.
