When you are shopping for data acquisition recorders, the first decision is whether you need the recorder itself or the consumable paper that keeps it running. The Lot of 10x Yokogawa B9573AN Folding Chart Recorder Paper Pads and the Kipp & Zonen BD 41 Chart Recorder Powers On/Untested sit on opposite sides of that question: one is a supply purchase, the other is a hardware purchase.
Quick verdict
If you already have a recorder that takes B9573AN paper, the Yokogawa pad lot is the more complete supply answer at $249. If you need an affordable recorder for $45 and are willing to complete the setup, the Kipp & Zonen BD 41 is the way to get started.
At a glance
| Product | Price | What you get | Best for |
|---|---|---|---|
| Yokogawa B9573AN Paper Pads (Lot of 10) | $249.00 | 10 pads of new B9573AN fanfold paper, each 66 ft long and 20 cm wide, non-thermal, 0-100 scale | Refilling a recorder that accepts B9573AN paper |

Where each product wins
The Yokogawa lot wins when you need chart paper in bulk and want new, consistent sheets. The Kipp & Zonen BD 41 wins when you want to buy a recorder at the lower end of the price spread and are comfortable handling the extras it needs. Neither item is a complete recording system by itself: the paper needs a recorder, and the recorder needs paper and power.
Product notes
Lot of 10x Yokogawa B9573AN Folding Chart Recorder Paper Pads
The Yokogawa lot is the supply-side choice. It contains ten pads of new B9573AN folding chart paper, and each pad is 66 ft long by 20 cm wide. The paper is non-thermal, so if your recorder uses that kind of fanfold paper, the lot gives you a steady stream of replacements without hunting for individual rolls. The strongest reason to pick it is the quantity and new condition. The limitation is that it is paper only; if you do not already own a recorder that accepts B9573AN paper, this purchase still leaves you without a way to record. It is also the larger upfront spend.
Kipp & Zonen BD 41 Chart Recorder Powers On/Untested
If you want the hardware rather than the consumable, the Kipp & Zonen BD 41 is the option to examine. This used chart recorder powers on and responds when buttons are pressed, which gives you a basic sign of life before you build a setup. It arrives without a power cord, and it is untested after that power-on check, so you should plan to supply the missing pieces. The reason to choose it is the low entry point for an actual recorder. The limitation is that button movement is not proof of accurate recording; on a used unit with no cord, you are accepting uncertainty in exchange for a smaller cash outlay.
Final choice by use case
Pick the Yokogawa paper lot if your data acquisition setup already includes a recorder that accepts B9573AN fanfold paper. Pick the Kipp & Zonen BD 41 if you are starting with a recorder-shaped gap and are prepared to add power and paper. If you have neither a recorder nor paper, the Kipp unit is the better first buy because it gives you the recorder; the paper can come later. For an existing recorder, the Yokogawa pads are the sustaining buy.
