How enquiries work

Quoted individually — so model, options and freight fit your port or plant.

STEP 1

Send the model or the job

Email or WhatsApp the model number — or just describe what you need to calibrate, the range and where it will be used.

STEP 2

Get the datasheet & quotation

You receive the full datasheet, available options, price and lead time. Questions on accuracy, inserts or accessories are answered before you decide.

STEP 3

Confirm & arrange delivery

Confirm the order details directly by email or WhatsApp and delivery is arranged to your address or your vessel's next port of call.

An independent supplier, not a marketplace listing

Personally run supply desk — one person from first question to delivery, no call centre. Practical instruments for marine teams, labs, plants and workshops, checked model by model.

  • Datasheets and honest specification checks before quoting
  • Model matching by application — temperature, pressure, process, electrical
  • Enquiries answered personally, typically within one working day
  • English communication by email and WhatsApp
