Hart protocol on-site debugging tool
Thread Content
When performing on-site calibration of instruments and no handheld operator is available, is there any useful Hart protocol modem that can be used with a laptop or smartphone for online calibration? Please advise those who know about such devices; if available, please send it to the email address: njzzl2000@126.com

There are indeed some that can be changed, but only the unit, range, and zero point can be adjusted; almost everything else cannot be changed, and the type of temperature sensor also cannot be altered.
Products of this kind are basically those without proper branding or quality certifications, but they’re not unusable either; some of their functions may be limited to some extent. It can be found on Taobao. Otherwise, you can send me a red envelope of 2000 yuan and I’ll buy it for you; I’ll refund you the extra amount. :lol
