For selecting an ammeter, what information should I have before contacting a distributor or sales rep?

1. What range do you need to cover (eg: 60-0-60 amps) Note: Some 60-0-60 and above ammeters require an external shunt. Be sure to verify in our catalog listing if one is needed.
2. Do you require lighting in the instrument
3. Diameter of the opening the instrument will be mounted in
4. What type of environment will the instrument be used in (eg: highway; high moisture; off-road; stationary equipment; etc)

If you wish to match the style of existing instruments you should also have the following:

1. If your current instruments are a Stewart Warner line, which line (Seaworthy, Heavy Duty Plus, etc) (see the Stewart Warner Products page for the product lines)
2. Bezel color wanted (black, polished, etc)
3. Dial face and graphics (black dial, white numbers, SAE symbols, etc)
4. Pointer type and color (eg: red with black hub)
