Soldering iron tester for measurement of tip temperature, leak voltage, and tip to ground resistance

  • For the daily maintenance of soldering station Control of "tip temperature", "leak voltage", and "tip to ground resistance" is required for a grounded soldering station for electronic components.

Human error-free operation

  1. AUTO HOLD function The measurement will end automatically when the displayed tip temperature is stabilized. Individual differences in temperature measurement can be minimized.
  2. Data send function (infrared) Measurement result can be sent to IoT capable soldering station, such as FN-1010, and be recorded automatically. Human errors in manual recording can be eliminated.

Long life sensor AS5000 (with certificate of conformance) is equipped as standard.

  • Lasts 30 times longer than a conventional sensor based on our in-house test
  • Save troubles of sensor replacements and enhance stable measurement for a long time.

MAX HOLD Function (Temperature measurement)

Max measured tip temperature will be displayed. This function can be useful for quality control of components and P.W.B.

Temperature Measurement Count Function

Number of tip temperature measurement will be automatically counted. This function can be useful for control of changing sensor.

AUTO ZERO Function

The zero point error of measuring instruments can be corrected by simply pressing the AUTO ZERO button and waiting for the display to return to normal.

Temperature probe

Use of a temperature probe makes it possible to measure the temperature of molten solder in a solder pot and hot air.

Pre-Order FAQs

View our full list of FAQs here

What is a pre-order?
Pre-orders are products that Hakko Product sells but do not maintain inventory on-hand. These usually include products with short shelf-lives or niche products.

Why should I pre-order?
Purchasing a pre-order item helps us order exactly the right amount of stock. It is a great way to secure an item and reduce wastage!

Having the item as pre-order means that we do not have to stock up our products unnecessarily, which may lead to faulty wiring or electronics in the long run. With pre-orders, you can be rest assured that the purchased products are brand-new and working well, not something that's been left on the shelf for years!

How does a pre-order work?
To secure your item, full payment is due at checkout. Manual payments must be received with the order number in order for us to proceed. When the item arrives at our warehouse, we will process the item within 2-3 business days. Each pre-order product will take approximately 6-8 weeks, but we will definitely ship it out earlier if we have existing stock from a previous shipment. 

How do I know if an item is a pre-order?
All pre-order items will be marked "pre-order" and will have an estimated shipping date in the description.

What if I want to purchase a pre-order item together with items that are in stock?
The entire order will be held until the pre-order item has arrived and all the items can be delivered together. If you would like your in-stock purchases to be delivered first, kindly purchase the items separately.

Pre-order Disclaimer
Because the item has not reached us, we can not guarantee the exact date your item will ship. Each pre-order item has an estimated shipping date but this may be subjected to changes without prior notice, due to many reasons out of our control (shipping, weather, stock level from Hakko Corporation etc).

Unfortunately, we are unable to cancel any orders after payment has been processed. If for any reason we are not able to fulfill your pre-order, we will reach out to you to settle refunds.

Should I contact Hakko Products for a more precise delivery estimate for my order?
Upon receiving your order, Hakko Products immediately requests for the delivery of the item. Our sales will reach out to you if there are any changes to the delivery timings. As mentioned above, we are unable to guarantee the exact date of shipment. We seek your patience and understanding in this matter.

I've been waiting for too long! Can I cancel my pre-order?
By adding to cart and proceeding with payment, you have agreed to the waiting time as stated in each product listing. We are unable to perform cancellations after payment has been processed. Refund requests for pre-orders will only be entertained if two weeks has passed since the stated waiting time and the product has not been delivered. 

For refunds due to defective or damaged goods, kindly reach out to our sales team.

Can't find a specific product?
Contact us via e-mail and we will look into bringing it to our stores! Sometimes, we may plan not to maintain physical inventory for certain products but if it’s something you are interested in, we can have a discussion on it.
