The Jumbo Bags is a very convenient and cost-effective flexible packaging container, which has been widely used in the world. However, there are some products that are very prone to metamorphose. If the product is not ventilated and breathable, the product can be musty and cause great loss. However, there will be high packaging and labor costs without the use of jumbo bags. So we don't seem to make any good choices, right?We can according to these weaknesses, the invention developed this kind of jumbo bags, It is also made of woven bags.the name is Breathable Jumbo Bags ,after rigorous testing, the breathable jumbo bags can not only has the advantages of Jumbo Bag, and can satisfy the ventilated breathe freely, very suitable timber, grain, such as a series of products need to be ventilated breathe freely. The customer can save a lot of packaging costs and labor costs. If necessary, please contact me and I will serve you wholeheartedly.

Technical principle: Eddy current maximum measurable plate: unlimited thinnest measurable plate: 1.0mm (40 mil)
The thickest measurable plate: 2.4mm (96 mil)
Probe insertion method: manual (or use probe holder)
Automatic plate thickness and hole diameter discrimination: no need to measure the smallest hole: 0.45mm (18mil) *
Maximum measuring hole: 2.0mm (80 mil) *
Hole wall Cu thickness measurement range: 2.5um-100um (0.1mil-4 mil)
Copper foil thickness measurement range: SP-100; Option ※
15um-100um (0.6mil-4.0mil)
It is suitable for measuring copper plating thickness in single-layer, double-layer and multi-layer boards.
Both the etched and unetched and tinned (Sn) and untinned (Sn) circuit boards can quickly measure the copper plating thickness in the hole.
The measurable aperture is as small as 0.45mm (18 mil); options ※
Dual function, measure the thickness of copper plating (PTH) in the hole of the circuit board, and the thickness of the copper foil of the copper plate. Options ※
High resolution LCD display, rugged keyboard.
Rechargeable battery and AC connector (200V)
The titanium-plated probe can be used for wet plate measurement without corroding the probe.
The only patent is the eddy current design, which is less affected by copper surfaces or etching pads than other similar instruments.
Built-in functions include: standard statistical functions, statistics and index functions represented by rectangular bars.
Can store up to 15,000 measurement data, and transmit measurement data through RS-232C. 
It is important to find defects in the production process of the PTH-1 / ITM-52 circuit board hole wall copper thickness and copper foil portable tester, so we developed the PTH-1 / ITM-52 portable thickness gauge , Measure the thickness of copper plating (PTH) in the hole of the circuit board, and also measure the thickness of the copper foil of the copper plate. PTH-1 / ITM-52 can provide answers quickly!
