Comparison

The 309 kit offers higher voltage measurement capabilities (1000VAC/1500VDC) compared to the 310 kit (750VAC/1000VDC). Additionally, the 309 kit features a higher resolution display with a 3-3/4 digit LCD and 4000 counts, and it provides better accuracy at 0.5%. In contrast, the 310 kit has a 3-1/2 digit LCD with 2000 counts and an accuracy of 1.5%.

However, the 310 kit is more cost-effective and provides all the essential features needed for most users in the blasting industry. It is priced significantly better, making it an ideal choice for those who require reliable performance without the additional capabilities of the 309 kit.
