The warranty will only be in effect if the Model No. of item supplied is not same as the model no. of item ordered (as mentioned in P.O./Metravi Website). If the item is reported to have any MANUFACTURING DEFECT, these defects have to be replicable at our location and verified mutually.
All invoices for our products are GST invoices. In case you are a GST registered individual or company and require the GST invoice for claiming GST ITC (GST Input Tax Credit), then you need to FILL UP your company name, registered billing address and GSTIN, without fail, BEFORE placing your order and paying for the same.

We will provide free of cost replacement of the product or authorise and accept a return only within Seven (7) days after the product has been delivered from our end. The warranty is only in effect if 1) Model No. of item supplied is not same as the model no. of item ordered (as mentioned on the Metravi Website). 2) The item has any MANUFACTURING DEFECT and these defects can be replicated at our service location and verified mutually. Our complete Returns Policy is available here. Important Note: At the time of taking the delivery of the items you ordered, please ensure that the product received is undamaged, is properly packed and acknowledge the same to the delivery person. Acceptance of package would imply checking and confirmation of correct and complete product set received in new and intact condition.

Yes, but you have to consider the problem of reflections. Usually the oven is hotter than the target. The target has some reflectivity so the thermometer measures the emitted energy as well as the reflected energy and indicates too high. This can be eliminated by using a sight tube, or possibly measuring the target at the exit of the oven. For glass, plastic films, and paper applications selection of the right thermometer can eliminate the reflection problem without a sight tube or looking at the exit of the oven.

Yes, the window has to be transparent for the wavelength of instrument you are using. For 1 to 2.6 microns we suggest quartz, for 3.4 to 5.4 microns we suggest Calcium Fluoride.

No, the infrared thermometers cannot see thru these interferences. However, in most industrial applications the dust and smoke are rising from the hot object and, if your eye was as fast as the IR thermometer you can see openings where the instrument has a clear line of sight. With the aid of a function called a peak picker the instrument can indicate the target temperature and ignore the cold readings caused by the dust and smoke.

For instruments that operate from the visible to 2.6 microns the color will usually change the emissivity. For wavelengths longer than 3 microns the color will not affect the emissivity. However, color does affect heating. Dark objects will get hotter than light colored objects.
