What knowledge do you need to pay attention to when choosing a furnace temperature tester?

Firstly Firstly, compare the parameters:

Usually, each furnace temperature tester will list the characteristics of their own product. Of course, the accuracy of these parameters cannot be fully trusted, but they can be used as a reference for initial selection, such as the fastest sampling frequency being 0. 01 seconds, definitely better than 0. One second is good, lithium-ion batteries are definitely better charged than nickel hydrogen batteries, USB communication is definitely better than RS232, and larger memory (sampling points) is definitely better than smaller memory

Secondly Physical dimensions:

The physical size mainly refers to the width of the furnace temperature tester. If the width of the furnace temperature tester itself is too wide, it will make it difficult for PCBs narrower than the furnace temperature tester to be placed on the track of the reflux furnace, which is very inconvenient. The suitable width (insulation box) is usually between 90-110mm. It should be as narrow as possible.

Thirdly Lead free process:

The main consideration for the lead-free process of the furnace temperature tester is the insulation effect of the insulation box. Usually, the temperature requirement for lead-free processes is 20-30 degrees higher than that of ordinary processes. Will this 20-30 degree cause instability in the internal IC of the furnace temperature tester? Causing inaccurate sampling temperature? On the contrary, if the lead-free process is OK, then the regular process is definitely OK.

Fourthly On site testing:

Before purchasing, it is necessary to conduct on-site testing as only on-site testing can identify issues

1. Stability of the instrument

By repeatedly testing the same reflux furnace for comparison, the problem can be identified.

2. Accuracy of the instrument

Different triggering temperatures and sampling frequencies can be set for testing and comparison.

3. Ease of use and completeness of software operations (especially for new companies, it is recommended to choose the simpler the operation, the better)

The operation software of a well-known brand is nested layer by layer, making people feel confused. Because the software is not structured or modular.

Without a solder paste warehouse and equipment warehouse, it is impossible to conduct process analysis. This is a major flaw.

4. After sales service (It is best to have a longer warranty period, the faster the repair cycle, and of course, the more technical support points, the better.)

I suggest purchasing from some professional domestic furnace temperature tester manufacturers, for example, Shenzhen Shihan Electronic Technology is a good choice!
